Viscosity robust weak Galerkin finite element methods for Stokes problems

<p style='text-indent:20px;'>In this paper, we develop a viscosity robust weak Galerkin finite element scheme for Stokes equations. The major idea achieving pressure-independent energy-error estimate is to use divergence preserving velocity reconstruction operator in the discretization of right hand side body force. optimal convergence results and pressure have been established paper. Finally, numerical examples are presented validating theoretical conclusions.</p>
