【Abstract】 By utilizing the properties of the interpolation on the element,mean-value and derivative delivery techniques,a Crouzeix-Raviart type nonconforming linear triangular finite element is applied to the hyperbolic type integro-differential equations and a new mixed element formulation is established.The optimal error estimates in H1-norm and in L2-norm are obtained.更多还原
