在这篇论文,我们在 ℝ【sub】d【/sub】 为随机的 Helmholtz 方程考虑有限元素方法和不连续的 Galerkin 方法(d = 2, 3 ) 。集中分析和为数字答案介绍的错误估计斧子。说明的近似斧子的精确性上的噪音的效果。数字实验斧子执行了验证我们的理论结果。
In this paper, we consider the finite element method and discontinuous Galerkin method for the stochastic Helmholtz equation in R^d (d = 2, 3). Convergence analysis and error estimates are presented for the numerical solutions. The effects of the noises on the accuracy of the approximations are illustrated. Numerical experiments are carried out to verify our theoretical results.
