Xiaoying Dai, Yan Pan, Bin Yang, Aihui Zhou

摘要:

本文研究二阶椭圆型偏微分方程特征值簇的自适应平面波离散。我们首先设计了一个后验误差估计器,并证明了上界和下界。基于后验误差估计,我们提出了一种自适应平面波方法。证明了自适应平面波逼近具有线性收敛速率和准最优复杂度。

英文摘要:

In this paper, we study the adaptive planewave discretization for a cluster of eigenvalues of second-order elliptic partial differential equations. We first design an a posteriori error estimator and prove both the upper and lower bounds. Based on the a posteriori error estimator, we propose an adaptive planewave method. We then prove that the adaptive planewave approximations have the linear convergence rate and quasi-optimal complexity.
