摘 要: 研究了一类完全非线性抛物方程的有限元方法,利用插值后处理技巧得到了其经典的双p次有限元方法半离散格式下的整体超收敛结果。 A kind of Strongly nonlinear parabolic equations are solved by the standard finite elements of degree p with the rectangular meshes. The global super-convergence is derived for the semi discrete scheme's error es- timate through post processing technology, without referring to the traditional Ritz-Volterra projection of the so- lution to the problem appeared in the previous studies.
