Nonlinear parabolic equations; Singularly perturbed equations; Sinc collocation method; Convergence analysis Abstract We propose a numerical method for solving singularly perturbed one-dimensional nonlinear parabolic problems. The equation converted to the nonlinear ordinary differential equation by discretization first in time then subsequently in each time level we use the Sinc collocation me...

Solving Systems of Linear Volterra Integro- Differential Equations by Using Sinc-Collocation Method

This paper presents meshfree method for solving systems of linear Volterra integro-differential equations with initial conditions. This approach is based on collocation method using Sinc basis functions. It's well-known that the Sinc approximate solution converges exponentially to the exact solution. Some numerical results are included to show the validity of this method.

Numerical solutions of two-dimensional linear and nonlinear Volterra integral equations: Homotopy perturbation method and differential transform method

A collocation method for the solution of nonlinear one-dimensional parabolic equations

In this paper, we develop a collocation method based on cubic B-spline to the solution of nonlinear parabolic equation εuxx = a(x, t)ut + φ(x, t, u, ux) subject to appropriate initial, and Dirichlet boundary conditions, where ε > 0 is a small constant. We developed a new two-level three-point scheme of order O(k + h). The convergence analysis of the method is proved. Numerical results are given...

Exact and numerical solutions of linear and non-linear systems of fractional partial differential equations

The present study introduces a new technique of homotopy perturbation method for the solution of systems of fractional partial differential equations. The proposed scheme is based on Laplace transform and new homotopy perturbation methods. The fractional derivatives are considered in Caputo sense. To illustrate the ability and reliability of the method some examples are provided. The results ob...
