摘要
本文利用积分恒等式证明了抛物型积分 -微分方程混合元解的超逼近性质 ,对常用 R- T元解通过插值后处理 ,得到整体超收敛 。
The superconvergence property of the mixed el em ent solution to parabolic integro-differential equation is demonstrated based o n the integral identities. For the well Known R-T elements, via interpolation p ost processing, the global superconvergence is obtained and the posteriori error estimates are also derived.
