The weak Galerkin method for a class of Gross-Pitaevskii type eigenvalue problems
Wei Lu, Qilong Zhai
This paper aims to employ the weak Galerkin method to solve a class of nonlinear eigenvalue problems. We proved the weak Galerkin scheme produces lower bound for the energy. Moreov…

The two-grid weak Galerkin method and enriched Crouzeix-Raviart element method for linear elastic eigenvalue problems
Wei Lu, Qilong Zhai
In this paper, we present a two-gird skill to accelerate the weak Galerkin method. By the proper use of parameters, the two-grid weak Galerkin method not only doubles the convergen…

The Weak Galerkin and Crouzeix-Raviart element method for elastic eigenvalue problems
Wei Lu, Hehu Xie, Qilong Zhai
In this paper, we first introduce an abstract framework to solve the eigenvalue problem by weak Galerkin (WG) method. By the application of the framework, WG method is proved to be…
