Abstract

In this paper‎, ‎the moving least square (MLS) approximation is implemented for the numerical solution of time fractional partial integro-differential equation (TFPIDE) on a bounded domain‎. ‎To establish the scheme‎, ‎we apply the finite difference scheme to approximate the time Caputo fractional derivative‎, ‎and we employ the composite trapezoidal quadrature rule for estimating integrals‎. ‎This approach is very convenient for solving TFPIDE since it does not require any need for mesh connectivity‎. ‎Then‎, ‎the problem solving turns into solution of a linear system‎. ‎The applicability and the validity of this method is investigated‎. ‎Furthermore‎, ‎the error estimate of the proposed method is provided‎. ‎Finally‎, ‎several numerical problems are solved which confirmed the theoretical findings‎. ‎
