【Abstract】 A class of finite difference schemes for degenerate parabolic systems are given. The existence of the discrete solutions for the finite difference systems is proved by using the prior estamation and Leray-schauder’s fixed-point theorem, and the convergence of the finite difference solutions is discussed.更多还原
