Weighted finite difference methods for a class of space fractional partial differential equations with variable coefficients

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≤12, and conditionally-stable for 12
