| 摘 要： | 利用双线性元和Nédéle?s元,对广义神经传播方程建立了最低阶自然满足Brezzi-Babuška条件的新混合元逼近格式.基于该混合元的高精度分析和插值后处理算子技术,在半离散格式下分别导出了原始变量的H1模及中间变量的L2模的超逼近性质和整体超收敛结果.当f(u)=f(X)时建立了一个具有二阶精度的全离散逼近格式,分别得到了原始变量的H1模的超逼近性和中间变量的L2模的最优误差估计. |

| Abstract: | A lowest order new mixed element approximate scheme with the bilinear element and Nédélec?s element for the generalized nerve conductive equations is proposed, which can satisfy Brezzi-Babuška condition automatically. Based on high accuracy analysis of the mixed element and interpolation post-processing technique, the superclose properties and superconvergence results of original variable in H1-norm and intermediate variable in L2-norm are deduced separately for semi-discrete scheme. At the same time, a second order fully-discrete scheme when is f(u) equal to f(X) is established and the superclose properties and the optimal order error estimates of original variable in H1-norm and intermediate variable in L2-norm are separately derived. |
| Keywords: | superclose properties and superconvergence results new mixed element the generalized nerve conductive equations semi-discrete and fully-discrete schemes |
