The DDGIC Method for Parabolic Integro-differential Equations
In this paper,DDGIC(Direct discontinuous Galerkin finite element method with interface correction)is applied to numerical solving the linear parabolic integro-differential equation,and the stability of semi-discrete scheme is discussed.Then with Crank-Nicolson discretion adopted in time direction,the fully discrete scheme is got,and the convergence is analyzed in detail.The numerical examples are given to verify the validity and the theoretical results.
