讨论了一类伪双曲型方程的一个H1-Galerkin非协调混合有限元方法.利用插值算子的特殊性质,在半离散和全离散格式下,得到了与传统混合有限元相同的误差估计且不需要满足LBB条件.
An H1 -Oalerkin nonconforming mixed finite element method is proposed to analyze a class of pseudo-hyperbolic equations. By use of the typical characteristics of the interpolation operatots, the same error estimates as in the classieal mixed methods for the semi-discrete and fully-discrete schemes are obtained without requiring the LBB consisiteney eondition.
