英文摘要A class of weighted finite difference methods (WFDMs) for solving a class of initial-boundary value problems of space fractional partial differential equations with variable coefficients is presented. Their stability and convergence properties are considered. It is proven that the WFDMs are unconditionally-stable for 0 <= r <= 1/2, and conditionally-stable for 1/2 < r <= 1, here r is the weighting parameter subjected to 0 <= r <= 1. Some convergence results are given. These methods, problems and results generalize the corresponding methods, problems and results given in [7,13,10]. Some numerical examples are provided to show the effectiveness of the methods with different weighting parameters. (C) 2009 Elsevier B.V. All rights reserved.
