Weak Galerkin finite element methods for parabolic equations (English)
0 references
The authors propose a new weak Galerkin method for solving parabolic equations. The method allows the usage of totally discontinuous functions in approximation spaces and preserves the energy conservation law. Both continuous and discontinuous time weak Galerkin finite element schemes are developed and optimal-order error estimates in both \(H^1\) and \(L^2\) norms are obtained. The method is then tested by a couple of examples.
