Under local differentiability assumptions on the nonlinear difference-operator necessary and sufficient conditions for convergence are presented, which turn out to be easy to verify.

The method is applied to an integro-differential equation of the mathematical physics and the numerical results are compared with the results of a usual explicite finite-difference method.

In the present study asymmetric linear basis functions are introduced which overcome this difficulty. In addition, parabolic basis functions are shown to be oscillation free and highly accurate for the working range of mesh sizes.
