Query: Weak Galerkin finite element method for Poisson's equation on polytopal
  meshes with arbitrary small edges or faces   In this paper, the weak Galerkin finite element method for second order
elliptic problems employing polygonal or polyhedral meshes with arbitrary small
edges or faces was analyzed. With the shape regular assumptions, optimal
convergence order for $H^1$ and $L_2$ error estimates were obtained. Also
element based and edge based error estimates were proved.
