【摘要】 本文讨论了非线性神经传播方程的P1-非协调矩形有限元逼近.首先在正则网格下,给出了其半离散格式下的误差估计和超逼近性质.其次,在各向异性网格下,给出了质量集中非协调有限元逼近格式,导出了L2-模和能量模的最优误差估计.
【Abstract】 In this paper, the P1-nonconforming rectangular finite element approximation for a class of nonlinear neural conduction equations is discussed. Firstly, under the regular meshes, the error estimates and the superclose property are presented with semidiscretiza-tion. Secondly, under the anisotropic meshes, the lumped mass nonconforming finite element scheme for this equations is presented, the L2- norm and the optimal energy norm error estimates are derived .
