汇报提要：In this research, meshfree collocation method is discussed for some multi-term time-space fractional order partial differential equations (PDEs). The time fractional derivatives are dealt with by Caputo fractional derivative operator and finite difference method while the space fractional derivative terms are dealt with by Riesz derivative operator, Riemann-Liouville derivative operator, Grunwald-Letnikov fractional derivative operator and then the space terms are discretized by meshfree radial basis function method based on Gaussian function. The stability and convergence of the proposed method are also discussed and the accuracy is assessed by L∞ (maximum norm).
