Sinc Methods and Chebyshev Cardinal Functions for Solving Singular Boundary Value Problems
Keywords:
Sinc method, Singular points, Double and single exponential transformation, Chebyshev cardinal functionsAbstract
In this paper we consider boundary value problems with singularity in equation or solution. To solve these problems, we apply single exponential and double exponential transformations of sinc-Galerkin and Chebyshev cardinal functions. Numerical examples highlight efficiency of Chebyshev cardinal functions and sinc-Galerkin method in problems with singularity in equations. It is illustrated that in problems with singular solutions, Chebyshev cardinal functions is not applicable. However, sinc-Galerkin method overcomes to this difficultly.
