摘　　要：利用修正的H1-Galerkin混合有限元方法研究了多维半线性双曲型积分微分方程,得到了半离散解及全离散解的最优收敛阶误差估计,该方法的优点是不需验证LBB相容性条件.Semilinear hyperbolic partial integro-differential equations are studied by modified H1- Galerkin mixed finite element methods. Optimal order error estimates are obtained for both semidiscrete and fully discrete solutions. The main feature of this method is that the approximations have the same rate convergence as in the classical mixed finite element methods without the LBB consistency conditions.
