A new low order nonconforming mixed finite element formulation for integro-differential equations of parabolic type
摘要
Abstract
In this paper, a new low order triangular nonconforming mixed finite element formulation was proposed for the integro-differential equations of parabolic type. By utilizing the properties of the interpolation on the element and derivative delivery techniques, the corresponding convergence analysis was presented, and the optimal error estimates in Hl -norm and in L2-norm were obtained.关键词
