To Estimate the Full Discrete H^1-Galerkin two Step Double Qu Bo Equation Mixed Element Error

研究一类半线性双曲波方程的时间两步H1-Galerkin混合元数值格式.该方法的特点是在空间方向考虑H1-Galerkin混合元方法,时间方向利用二阶两步方法.给出未知函数和梯度函数详细的先验误差理论分析.

A class of Semilinear double Qu Bo equations in time the two step H1 - Galerkin mixed finite element numerical format are studied. The characteristic of this method is to consider the H1 - Galerkin mixed finite element method in space; time orientation by using two order two step method. The priori error analysis of unknown function and the gradient function are proposed.
