Equivalence of Weak Galerkin Methods and Virtual Element Methods for Elliptic Equations

Abstract

We propose a modification of the weak Galerkin methods and show its equivalence to a new version of virtual element methods. We also show the original weak Galerkin method is equivalent to the non-conforming virtual element method. As a consequence, ideas and techniques used for one method can be transferred to another. The key of the connection is the degree of freedoms.

Some arguments are not exactly correct
