【摘要】 给出一个新的高次Wilson元,证明了它的收敛性,获得了解的超逼近性质,并且利用插值后处理技术得到了有限元解的整体超收敛.在此基础上还得到了解的后验误差估计.更多还原

【Abstract】 A new higher order Wilson element is presented,the convergence and superclose properties of this element are proved.Then the interpolation postprocessing technique is used to obtain the global superconvergence and a posteriori error estimate of higher accuracy.更多还原
