Nonconforming \(H^{1}\)-Galerkin mixed FEM for Sobolev equations on anisotropic meshes
The authors consider a nonconforming mixed finite element approximation for the Sobolev equation on anisotropic meshes. The convergence order is provided in the both cases of semi and full discretization schemes. Error estimates are obtained without using the Ritz-Volterra projection.
