摘要

In the present work we are going to solve the boundary value problem for the quasilinearparabolic systems of partial differential equations with two space dimensions by the finitedifference method with intrinsic parallelism. Some fundamental behaviors of general finitedifference schemes with intrinsic parallelism for the mentioned problems are studied. By themethod of a priori estimation of the discrete solutions of the nonlinear difference systems,and the interpolation formulas of the various norms of the discrete functions and the fixed-point technique in finite dimensional Euclidean space, the existence of the discrete vectorsolutions of the nonlinear difference system with intrinsic parallelism are proved. Moreoverthe convergence of the discrete vector solutions of these difference schemes to the uniquegeneralized solution of the original quasilinear parabolic problem is proved.
