摘要/Abstract

摘要：

利用Wilson元研究了Extended Fisher-Kolmogorov（EFK）方程的间断有限元逼近格式.在不需要后处理技术的前提下，通过对非线性项采用新的分裂技术，分别得到了半离散和线性化欧拉全离散格式下原始变量$u$和中间变量$v=-\triangle u$的$O(h^{2})$和$O(h^{2}+\tau)$阶的收敛性结果，正好比通常的关于Wilson元的误差估计高出一阶.这里，$h$，$\tau$表示空间剖分参数和时间步长.

关键词: EFK方程, 间断有限元, Wilson元, 半离散和全离散格式, 收敛性

Abstract:

The discontinuous Galerkin finite element approximation schemes for the Extended Fisher-Kolmogorov (EFK) equation are studied by using the Wilson element. Without using the technique of postprocessing technique, the convergence results with order $O(h^{2})/O(h^{2}+\tau)$ for the primitive solution $u$ and intermediate variable $v=-\triangle u$ are obtained for the semi-discrete and linearized Euler fully discrete approximation schemes respectively through a new splitting technique for the nonlinear terms. The above results are just one order higher than the usual error estimates of the Wilson element. Here, $h$ and $\tau$ are parameters of the subdivision in space and time step, respectively.

Key words: EFK equation, Discontinuous Galerkin finite element, Wilson element, Semi-discrete and fully-discrete schemes, Convergence
