A novel nonconforming uniformly convergent finite element method in two dimensions
A new analysis of the nonconforming Galerkin finite element method for solving linear elliptic singularly perturbed boundary value problems for rectangular domains is given. In the case of ordinary boundary layers, the method is shown to be uniformly convergent with respect to the perturbation parameter in the energy form.
