| Abstract: | This paper is concerned with the application of the symmetric Galerkin method to the numerical solution of a kind of singular boundary value problems in one space. With the aid of Green function, we derive the desired error estimates in the maximum norm for the linear problem. Furthermore, we extend these results to the nonlinear problem. Finally, we present some numerical results which illustrate and support our theoretical results.
