چکیده
|
A class of two-parameter singularly perturbed nonlinear second order ordinary differential equations is considered in this article. a fitted mesh method which is a combination of finite difference scheme and a shishkin mesh is developed to solve the problems. the method is proved to be essentially first order parameter independent convergent. numerical experiments support the established theoretical results.
