Enhanced Error Estimates for Augmented Subspace Method with Crouzeix-Raviart Element
Zhijin Guan, Yifan Wang, Hehu Xie +1
In this paper, we present some enhanced error estimates for augmented subspace methods with the nonconforming Crouzeix-Raviart (CR) element. Before the novel estimates, we derive t…

Augmented Subspace Scheme for Eigenvalue Problem by Weak Galerkin Finite Element Method
Yue Feng, Zhijin Guan, Hehu Xie +1
This study proposes a class of augmented subspace schemes for the weak Galerkin (WG) finite element method used to solve eigenvalue problems. The augmented subspace is built with t…
