Abstract
A numerical method based on finite difference method with variable mesh is given for second order singularly perturbed self-adjoint two point boundary value problems. The original problem is reduced to its normal form and the reduced problem is solved by FDM taking variable mesh(geometric mesh). The maximum absolute errors max i | y ( x i ) - y i | , for different values of parameter Ļµ, number of points N, and the mesh ratio r, for three examples have been given in tables to support the efficiency of the method.
