“…Finally we should mention, that even in the relatively simple case of elliptic interface problems involving a smooth non-intersecting interface of coefficient jump, the theoretical proof of convergence of the various proposed finite difference schemes is usually missing. The only exceptions are presented in [21] using discrete maximum principle for a second order scheme, and [12] using numerically verified discrete maximum principle for a fourth order scheme. The compact 9-point schemes considered in the present paper possess the M -matrix property, that guarantees the discrete maximum principle for the numerical solution.…”
