Abstract:A new nonconforming mixed finite element formulation is proposed for the integro-differential equation of parabolic type. By utilizing the properties of the interpolation on the element and derivative delivery techniques on the square meshes, the corresponding convergence analysis is presented, and the optimal order error estimates in H1-norm and in L2-norm are obtained.
Keywords:integro-differential equation: nonconforming finite element: new mixed finite element formulation: optimal order error estimate
