The existence and uniqueness of solutions of the Dirichlet problem for the difference Poisson type equation are proved. We study in detail properties of the discrete model including the limiting process in the two-dimensional Euclidean case.13 pagesMathematical PhysicsAnalysis of PDEs35Q60, 39A12, 39A70text
