Numerical solution of singular boundary value problems via Chebyshev polynomial and B-spline

In this paper, we present B-spline method for numerically solving singular two-point boundary value problems for certain ordinary differential equation having singular coefficients. These problems arise when reducing partial differential equation to ordinary AM differential equation by physical symmetry. To remove the singularity, we first use Chebyshev economization in the vicinity of the singular point and the boundary condition at a point x = delta (in the vicinity of the singularity) is derived. The resulting regular BVP is then efficiently treated by employing B-spline for finding the numerical solution. Some examples have been included and comparison of the numerical results made with other methods. (C) 2003 Published by Elsevier Inc.
