Bifurcation theory of flexible exchange rates in the new Keynesian model: An application
Mustafa Bayram and Anil Burcu Ozyurt Serim
Bifurcation, Hopf bifurcation, new-Keynesian macroeconometrics, stability
Formerly, the fixed exchange rate was identified as the main policy in economy, but in time it has been proved that the applicability of this policy in economy is not possible. With the new Keynesian approach, this situation has led to the formation and development of new monetary policies. The Keynesian model monetary policy in this article has been based on the flexible exchange rate. By applying the bifurcation theory on monetary policy parameters the interrelations among the inflation target value, the output gap and the equilibrium real interest rate were examined.

Huseyin Kocayigit, Muhammed Cetin and Beyza Betul Pekacar
Dual Lorentzian space, dual Frenet frame, dual curve of constant breadth
In this paper, we study dual curves of constant breadth in dual Lorentzian space D. We obtain the differential equations characterizing dual curves of constant breadth in D and we introduce some special cases for these dual curves. Furthermore, we obtain that the total torsion of a closed dual spacelike curve of constant breadth is zero while the total torsion of a simple closed dual timelike curve is equal to 2npi, (n in Z).

An efficient approach to numerical study of the coupled-BBM system with B-spline collocation method
Khalid Ali, Kamal Raslan, Talaat S. EL-Danaf
Collocation method, cubic trigonometric B-splines method, coupled-BBM system.
In the present paper, a numerical method is proposed for the numerical solution of a coupled-BBM system with appropriate initial and boundary conditions by using collocation method with cubic trigonometric B-spline on the uniform mesh points. The method is shown to be unconditionally stable using von-Neumann technique. To test accuracy the error norms2L, ?L are computed. Furthermore, interaction of two and three solitary waves are used to discuss the effect of the behavior of the solitary waves after the interaction. These results show that the technique introduced here is easy to apply. We make linearization for the nonlinear term.

Application of intuitionistic fuzzy soft sets in decision making based on real life problems
Anjan Mukherjee, Sadhan Sarkar, Somen Debnath
Fuzzy sets, soft sets, Fuzzy soft sets, intuitionistic fuzzy soft sets, intuitionistic fuzzy aggregation.
In 1999, Molodtsov introduced soft set theory which is a new mathematical tool for dealing with uncertainties and is free from the difficulties affecting the existing methods. Research works on soft set theory are progressing rapidly. Combining soft sets with fuzzy sets and intuitionistic fuzzy sets, Maji et al. , defined fuzzy soft sets and intuitionistic fuzzy soft sets which are rich potentials for solving decision making problems. It has been found that soft set, fuzzy set and rough set are closely related concepts. In this work, we define intuitionistic fuzzy soft set aggregative operator that allows constructing more efficient decision making method. Finally, we give an example which shows that the method can be successfully applied to many problems that contain uncertainties.

Insurance in Turkey and main problems of the sector
Alaattin Firat
Insurance, insurance in Turkey, insurance sector, the problems of insurance sector, the features of the insurance sectors.
In this study, by handling private insurance sector in Turkey and the problems of the sector as a whole, the last stage that the insurance business in Turkey has reached has been evaluated. Basically, because of the fact that the most of the people had fatalistic understanding, religious leaders approached the concept of insurance negatively and adequate information hadn’t been gotten about insurance, the settlement of the idea of insurance in Turkey came true after 150 years later, at the end of 19. Century compared with Europe. As a result of changing conditions, Turkey is in 63rd in accordance with the insurance density on the world countries’ rank, and is in 39th rank in accordance with the primary production. In spite of this, when we examine the studies according to per person criteria, it is seen that the premium rate per person in Turkey is fortieth level among developed countries. The top reason of the fact that insurance business in Turkey hasn’t risen to the requested level is that there is still fatalistic society understanding; and also, the fact that insurance understanding hasn’t been settled, and hitching and late payment on damage payments of insurance firms, and not having an effective promotion and marketing understanding are seen as the primary reasons. Despite of these negative factors, in Turkey being an developing country, the insurance sector has a potential to show at least a threefold improvement from todays’ position in a short time in case of precautions to be taken by state and applying these precautions by seriousness.

A numerical method based on the fnite element method is used for an investigation of
viscous, incompressible fuid fowing in a channel with slowly varying cross-section
with absorbing walls. The proposed mathematical model can be applied to understand
the fow behaviour of a fuid in renal tubules. The method is not restricted by the
parameters in the problem such as wave number, permeability parameter, amplitude
ratio and Reynolds number. The effects of these parameters on the transverse velocity
and mean pressure drop is studied and the results are presented graphically. Results
show that the parameters cause a signifcant change on the fow.

Numerical solution of the neutral functional-differential equations with proportional delays via collocation method based on Hermite polynomials
Birol Ibis, Mustafa Bayram
Hermite collocation method (HCM), collocation points, Hermite polynomials, neutral functional-differential equations (NFDEs).
In this paper, a collocation method based on Hermite polynomials is presented for the numerical solution of the neutral functional-differential equations (NFDEs) with proportional delays. By using Hermite polynomials and collocation points, NFDEs and the given conditions are transformed into matrix equation which corresponds to a system of linear algebraic equations with unknown Hermite coefficients. Hence, by solving this system, the unknown Hermite coefficients are computed. In addition, some numerical examples are given and comparisons with other methods are made in order to demonstrate the validity and applicability of the proposed method.

Non-polynomial spline method for solving the generalized regularized long wave equation
Talaat S. EL-Danaf, K. R. Raslan, Khalid K. Ali
Non-polynomial spline, generalized regularized long wave equation, solitary waves, solitons.
In this paper, non-polynomial spline method for solving the generalized regularized long wave (GRLW) equation are presented. In this paper, we take deferent spline functions. The stability analysis using Von-Neumann technique shows the scheme is marginally stable. To test accuracy the error norms L_{2} , L_{\infty } are computed. Also, the change in conservation quantities are evaluated which are found to be very small. To illustrate the applicability and efficiency of the basis, we compare obtained numerical results with other existing recent methods. Moreover, interaction two and three solitary waves are shown. The development of the Maxwellian initial condition into solitary waves is also shown and we show that the number of solitons which are generated from the Maxwellian initial condition can be determined.

A general evaluation on life insurance in Turkey
Alaattin Firat
Insurance, life insurance, insurance in Turkey, reasons for not developing.
Insurance is a contract that aims to compensate the insured who suffers from
building, object, property or life damage as a result of natural disasters such
as fires, accidents, deaths and so on, by the insurer. In other words, it
compensates for the damages and tries to reduce the uncertainty and risks of the future.
In this study, we have studied Life Insurance in Turkey, a Middle East country
whose 90\% of the population is Muslim and is in the category of developing
countries.
As a result, we observe that in countries like Turkey and similar countries life
insurance does not develop at the desired level due to religious, technological
and economic reasons.

A numerical study of a fluid flow by transforming a non-uniform wavy channel
Tesfahun Berhane, Getachew Adamu
Fluid flow, non-uniform channel, finite difference method.
An incompressible viscous flow in a non-uniform wavy channel with slowly varying cross section with absorbing walls is numerically studied. The governing equations are solved using finite difference method by transforming the irregular boundary of the region of the problem to rectangular region. The effect of different parameters on the transverse velocity and the mean pressure drop is analyzed. The results obtained using this method is in a good argument with results obtained by other numerical methods without transforming the wavy channel to rectangular channel. The results are presented by using tables and graphs.

Bernoulli polynomials, Bernoulli wavelets, Volterra-Fredholm fuzzy integral equations, Integration of the cross product, Product matrix, Coefficient matrix.
This work, Bernoulli wavelet method is formed to solve nonlinear fuzzy Volterra-Fredholm integral equations. Bernoulli wavelets have been Created by dilation and translation of Bernoulli polynomials. First we introduce properties of Bernoulli wavelets and Bernoulli polynomials, and then we used it to transform the integral equations to the system of algebraic equations. We compared the result of the proposed method with the exact solution to show the convergence and advantages of the new method. The results got by present wavelet method are compared with that of by collocation method based on radial basis functions method. Finally, the numerical examples explain the accuracy of this method.

Deriving Behaviour of Hodgkin Huxley model with fever dynamics: A computational study
Hasan Eskalen , Sukru Ozgan
Hodgkin-Huxley, exponential integrate and fire, I-V curve, reduction.
A single neuron can be modeled by the set of differential equations. Hodgkin-Huxley (HH) model, the one of the most famous neuron model, can be considered as a dynamical system with four independent variables. Here we studied to reduce the number of differential equation required for conductance based HH model under strong inhibitory noise. Exponential Integrate and Fire (EIF) model, one independent variable, is used as a reduced model of HH model by using current-voltage (I-V) curve of the original model. The required reduction parameters are determined from this curve. The behaviour of HH model and its reduced EIF (rEIF) model are in good agreement in sub-threshold level. Above-threshold behaviour of reduced EIF model and original model compared in terms of threshold voltage under strong inhibitory noise. Our numerical simulations clearly show that sub-threshold behaviour of HH model perfectly reduced to rEIF model.

An application of logistics regression model to determining the credit suitability and impacting factors in a special bank branch
Muharrem Unver, Berge Sahin and Filiz Ersoz
Bank, logistic regression (LR), factors affecting for loan.
There are quite complicated rules and constraints that can be imposed by the bank when the loan issued. Bank branches, which play a direct role in the credit, must accurately determine the customer's credit request to eliminate these difficulties and create an effective payment system according to the customer. In the study, 100 random loan applications made in 2016 of a bank branch operating in the Black Sea Region were examined. These customer demands are affecting customer characteristics. The "Logistic Regression Model" was created to predict creditworthiness according to the identified fugitives. In the model, customer age, education, marital status, debt grade, credit card debt, other debts, cross product are the variables. These are statistically significant in terms of marital status, gender, cross product, or creditworthiness. However, various variables such as debt income ratio, credit card debt, and other debts are statistically significant and affect credibility to negatively. In addition, occupational, income and educational constraints were found to be meaningless. With this model, the factors affecting the credit were evaluated. As a result of the study, the bank branch will benefit from the statistical model in which it is created, to evaluate according to the customer characteristics in its portfolio, and to give more credit to branch customers.

Abdel-Salam G. Abdel-Salam, Mohammad D.Mollazehi, IbrahimA. El Feky, Yousuf A. Dorra, Irfan J. Ismail and Salman Umer
Scoring System, bowling, conditional modeling, categorical data analysis, cumulative logit model.
This study introduces a new bowling scoring system and tests its consistency with the current scoring system with respect to preserving player placements. A comprehensive simulation study for different scenarios; two-player, three-player, and four-player games performed. The simulations empirically quantify the likelihood of experiencing concordant results between the two (current and new) systems. The simulation study revealed that the percentage of times that the current and new scoring systems yield the same placements at least 85\% when two players compete, at least 66\% of the time when three players compete, and at least 43\% of the time when four players compete regardless of the ability levels of the players. A comparison study using real bowling data-sets have been done and showed the consistence for the new scoring system with the current one. However, the new scoring system is easy to calculate, understand and to be implemented.

Modelling and optimization of multi-item solid transportation problems with uncertain variables and uncertain entropy function
Hasan Dalman
Uncertain entropy function, multi-item solid transportation problem, uncertain multiobjective optimization, uncertainty theory.
This paper concentrates on modeling of the uncertain entropy multi item solid transportation problem, in which the supply capacities, demands, conveyances and transportation capacities are thought to be uncertain variables due to the obvious uncertainty of information. In general, the transportation cost in the transportation problem is employed by the optimization aim, while the dispersals of trips among sources, destinations, and conveyances are often ignored.
In order to minimize both transportation penalties and maximize entropy value which guarantees uniform transportation of products from sources to destinations via conveyances, this paper holds entropy function of dispersals of trips among sources, destinations, and conveyances as a second objective function. Inside the construction of uncertainty theory, the uncertain entropy function for transportation models is first proposed here. Thus the model is turned into its crisp equivalent by using uncertainty theory, which can be solved by applying minimizing distance optimization method. Finally, a numerical experiment is given to illustrate the models.

A mathematical analysis of a 2D model for tumor angiogenesis: An initial data perturbation approximation
Serdal Pamuk and Irem Cay
Tumor angiogenesis, linearization, perturbation, approximation.
We present a 2D - mathematical model for tumor angiogenesis and solve it by linearizing it using an initial data perturbation approximation method. This method is a well-known and highly effective method to obtain solutions of coupled non-linear differential equations. This method shows that a few terms of the obtained approximate solution are enough to get an idea about the movement of endothelial, macrophage and pericyte cells in the extra cellular matrix, which are needed for the initiation of tumor angiogenesis. MATLAB-generated figures are provided.

Average weakly edge domination number in graphs
Mehmet Balci and Pınar Dundar
Average weakly edge domination, edge distance, vulnerability.
Communication is supposed to be continuous in a network design. It is important for a network to be tough so that communication is not interrupted in case any damage. In this paper, it is investigated how to decide which graph model to choose, when a selection is needed to make
between different graphs to be used for a network model when all known vulnerability measures are same. We introduce the concept of the average weakly edge domination number of a graph as a new vulnerability measure. We establish relationships between the average weakly edge domination number and some other graph parameters, and the extreme values of given measure among all graphs and average weakly edge domination number for some families of graphs. Also a polynomial time algorithm with complexity O(n^3) is given.

Tuba Agirman Aydin, Mehmet sezer and Huseyin Kocayigit
Timelike curve of constant breadth; Bernstein polynomials; Linear differential equations, Minkowski 3-space.
In this study, we first show that the system of Frenet-like differential equation characterizing timelike curves of constant breadth is equivalent to a third order, linear, differential equation with variable coefficients. Then, by using a rational approximation based on Bernstein polynomials, we obtain the set of solution of the mentioned differential equation under the given initial conditions. Furthermore, we discuss that the obtained results are useable to determine timelike curves of constant breadth in Minkowski 3-space E_1^3.

Chebyshev wavelets, collocation method, nonlinear differential equations, quasilinearization technique, approximate solution.
Chebyshev wavelets operational matrices play an important role for the numeric solution of rth order differential equations. In this study, operational matrices of rth integration of Chebyshev wavelets are presented and a general procedure of these matrices is correspondingly given. Disadvantages of Chebyshev wavelets methods is eliminated for rth integration of Y(t). The proposed method is based on the approximation by the truncated Chebyshev wavelet series. Algebraic equation system has been obtained by using the Chebyshev collocation points and solved. The proposed method has been applied to the three nonlinear boundary value problems using quasilinearization technique. Numerical examples showed the applicability and accuracy.

Numerical simulation of thermal deformation of a rough slider bearing and its Asperities: special reference on load generation in parallel sliders
Getachew Adamu and Prawal Sinha
Longitudinal roughness, transverse roughness, thermal deformation, load capacity.
The present work is an attempt to analyze the influence of thermal deformation on the thermo-hydrodynamic lubrication of infinitely long tilted pad slider rough bearings. As a consequence of heating the slider is deformed and is assumed to take a parabolic shape. Also the asperities expand leading to smaller effective film thickness. Two different types of surface roughness are considered: longitudinal roughness and transverse roughness. Christensen’s stochastic approach is used to derive the Reynolds-type equations. Density and viscosity are considered to be temperature dependent. The modified Reynolds equation, momentum equation, continuity equation and energy equation are decoupled and solved using finite difference method to yield various bearing characteristics. From the numerical simulations it is observed that the performance of the bearing is significantly affected by the thermal deformation of the slider and asperities and even the parallel sliders seem to carry some load.

This problem focuses on the laminar flow of a nanofluid in an inclined permeable parallel walls. We assume that the lower wall is wavy while the upper wall is flat with Dufour effects, Soret effects, and a magnetic field effect with boundary conditions been convective. The rectangular coordinate system has been used to present the model for this problem. It also incorporates the effect of
thermophoresis parameter and Brownian motion. The obtained similarity solution is dependent on the thermophoresis number (Nt ), Darcy number (Da), Magnetic parameter (M), Dufour (DU) number, Soret (Sr) number, Brownian motion (Nb), Lewis number (Le), Prandtl number (Pr). It is found that at the wavy wall, the fluid flow back.

Stability analysis of infectious diseases model in a dynamic population
Joseph A. Akinyemi, Micheal O. Adeniyi and Angela U. Chukwu
Basic reproduction number, dynamic population, asymptotically stable , Lyapunov function, equilibrium point.
The stability analysis of infectious disease model in a dynamic population is studied.The recruitment rate into the susceptible population is introduced since the population is dynamic thereby allowing a varying population as a result of migration and birth. The model exhibited two equilibria: the disease-free and endemic. The local stability of the model is asymptotically stable when and unstable when. The global stability analysis of the disease-free shows that the system is globally stable when the first derivative of the Lyapunov function is negative.

Darboux transformation for soliton solutions of the modified Kadomtsev-Petviashvili-II equation
Mohamed R. Ali
Darboux transformation , soliton solutions , modified Kadomtsev-Petviashvili-II equation.
Soliton solutions as far as hyperbolic cosines to the modified Kadomtsev–Petviashvili II equation are displayed. The behaviour of each line soliton in the far region can be characterized analytically. It is revealed that under certain conditions, there may appear an isolated bump in the interaction centre, which is much higher in peak amplitude than the surrounding line solitons, and the more line solitons interact, the higher isolated bump will form. These results may provide a clue to generation of extreme high-amplitude waves, in a reservoir of small waves, based on nonlinear interactions between the involved waves.

Lucas collocation method to determination spherical curves in euclidean 3-space
Muhammed Cetin, Huseyin Kocayigit and Mehmet Sezer
Spherical curves, Frenet frame, Lucas polynomial and series, collocation points, differential equation.
In this study, we give a necassary and sufficient condition for an arbitrary-speed regular space curve to lie on a sphere centered at origin. Also, we obtain the position vector of any regular arbitrary-speed space curve lying on a sphere centered at origin satisfies a third-order linear differential equation whose coefficients is related to speed function, curvature and torsion. Then, a collocation method based on Lucas polynomials is developed for the approximate solutions of this differential equation. Moreover, by means of the Lucas collocation method, we approximately obtain the parametric equation of the spherical curve by using this differential equation. Furthermore, an example is given to demonstrate the efficiency of the method and the results are compared with figures and tables.

Approximate solution of the problem of delayed variable boundary value by the CAS wavelet method
Elif Deniz Ozturk, Arzu Aykut and Ercan Celik
Fredholm-Volterra integral equations, differential equation with retarded argument, CAS wavelet method.
In this paper, by considering the boundary value problem
x'' (t)+a(t)x(t-τ(t))=f(t), (0≤t≤T)
x(t)=φ(t)(λ_0≤t≤0), x(T)=x(c)(0<c<T)
such that τ(t)≥0 is an arbitrary continous function on 0≤t≤T, Fredholm-Volterra Integral Equation, which is equivalent to this problem, was written considering the boundary value problem. Under certain conditions, the Fredholm-Volterra integral equation was transformed into the Fredholm integral equation. The solution of this integral equation is approximated by the "CAS Wavelet" method. Thus, an approximate solution to the given boundary value problem was found.

Samuel Abu Somma, Ninuola Ifeoluwa Akinwande, Roseline Toyin Abah, Festus Abiodun Oguntolu and Florence Dami Ayegbusi
Semi-analytical, mathematical modeling, yellow fever, dynamics, differential transformation method.
In this paper we use Differential Transformation Method (DTM) to solve the mathematical modeling of yellow fever dynamics incorporating secondary host. The DTM numerical solution was compared with the MAPLE RungeKutta 4-th order. The variable and parameter values used for analytical solution were estimated from the data obtained from World Health Organization (WHO) and UNICEF. The results obtained are in good agreement with Runge-Kutta. The solution was also presented graphically and gives better understanding of the model. The graphical solution showed that vaccination rate and recovery rate play a vital role in eradicating the yellow fever in a community.

Robust Numerical Solution for Solving Elastohydrodynamic Lubrication (EHL) Problems using Total Variation Diminishing (TVD) Approach
Peeyush Singh and and Prawal Sinha
TVD schemes, multi-level, variational inequality, elastohydrodynamic lubrication, defect-correction.
In this study, we propose a class of total variation diminishing (TVD) schemes for solving pseudo-monotone variational
inequality arises in elastohydrodynamic lubrication point contact problem.
A limiter based stable hybrid line splittings are introduced on a hierarchical multi-level grid.
These hybrid splittings are designed by use of diffusive coefficient and mesh dependent switching parameter in the computing domain of interest.
The spectrum of illustrated splittings is derived with the help of well known local Fourier analysis (LFA). Numerical tests validate the performance of the scheme and its competitiveness to the previous existing schemes. Advantages of proposed splittings are observed in the sense that it reduces computational complexity (up to ($O(n\log n)$)
and solve high order discretization directly (no defect-correction tool require) without perturbing the robustness of the solution procedure (i.e. it works well for a large range of load parameters).

Numerical investigation of entropy generation in unsteady MHD generalized Couette flow with convective cooling
O. Kigodi, M. H. Mkwizu, A X Matofali, M. A. Selemani, N. Ainea, S. Khamis and G. K. Karugila
Magneto hydrodynamic (MHD), Couette flow, nanofluids, entropy generation.
This study aimed at making an investigation on entropy generation in unsteady MHD generalized couette flow with convective cooling. Specifically the study intended to; develop flow model for a case of nanofluid in a channel, determine the effect of different parameters on velocity, temperature and entropy generation and to determine the effect of magnetic field on the flow on an entropy generation. Also the study aim to come up with distinctively recommendation on dynamics of entropy generation, temperature variation and velocity profiles in unsteady MHD flow with convective cooling. Findings showed that an increase in nanoparticles and Reynolds number leads to increase in the velocity while pressure gradient, MHD and nanofluid fraction held constant. It is evidently that Alumina-water nanofluid tends to raise the velocity profile faster than Copper-water nanofluid. Also the results show that an increase in Eckert number causes the decrease in temperature profile. Further, it was noticed that Copper-water nanofluid tends to raise the temperature profile faster than Alumina-water nanofluid. More interestingly it was observed that the entropy generation rises as the result of increase in Eckert number. Also it is noticed that entropy generation rises in lower plate but when it comes closer the upper plate the entropy generation rate starts to fall as the result of increase in nanoparticles.

Antireduction method for the exact solutions of the porous media equation
Serdal Pamuk
Antireduction method, Exact solution, Porous Media equation, Porosity.
By the antireduction method we obtain the exact solutions of porous media equation, a nonlinear heat equation that usually arises in mathematical biology, nonlinear problems of mass transfer and combustion theory. This method requires construction of a number of ansatzes that reduce nonlinear heat equations to a system of ordinary differential equations. Solving this system yields the exact solution of the given nonlinear heat equation. Our theoretical results are compared with some other results that appear in the research literature. In addition, numerical results are provided for various values of the porosity constant.

New results on delay dependent stability for a class of nonlinear systems with additive time delay
Yener Altun
LKF, Delay dependent stability, Time delay, Additive time delay, LMI.
In this manuscript, the issue of delay dependent stability for a class of
additive delayed nonlinear systems has been searched. By constructing an appropriate
Lyapunov-Krasovskii functional (LKF), some new stability criteria are established in
terms of linear matrix inequalities (LMIs) which can be easily tested. This manuscript
also presents a new result of stability analysis for a class of nonlinear systems with two
additive time delays. Finally, two illustrative examples with numerical simulations have
been given to show the applicability of the obtained theoretical results by using the
MATLAB-Simulink.

P. Priyadharshini, M. Vanitha Archana, Elsayed Elsayed, D. Vivek
Magnetohydrodynamic, Viscoinelastic Nanoﬂuid, Stretching Sheet,
Biomedical procedures such as surgical glue, knee replacement surgery, blood diagnostic and many others can exhibit the signi?cance of viscoinelastic behavior with non-newtonian characteristics is analysed. Present article addresses the ?ow design is to accentuate the thermophysical characteristics of electrically conducting viscoinelastic nano?uid ?ow produced by a stretched surface. The impacts of Brownian motion and thermophoresis on viscoinelastic nano?uid are accounted in the presence of heat and mass transfer convective states. The modeled partial di?erential equations are transmuted into nonlinear ordinary
di?erential equations employing similarity transformations to facilitate the computation procedure. The solution of the achieved boundary value problem is procured numerically by utilizing a program written with sti?ness-changing methodology. The manners of controlling parameters on the ?uid velocity, temperature, and concentration pro?les are spotlighted via graphs. Finally, by changing the pertinent parameters, the Machine Learning technique is used to investigate critical properties of ?uid ?ow near the wall, such as skin friction coe?cient, Nusselt number, and Sherwood number. The e?ects of driving parameters are illustrated in a graphical and tabular format. The precision of the current methodology is validated by a comparison between the current and previous ?ndings.

linear and non-linear heat equations. This method is based on the
use of a general Lagrange multiplier in the construction of
correction functional for the equation. In comparison with existing
techniques, this method is very powerful, and the solution procedure
is very simple since it uses only the prescribed initial condition.
Some analytical results are presented.
