摘要：

An optimal order multigrid method for the lowest-order Raviart-Thomas mixed triangular finite element is developed. The algorithm and the convergence analysis are based on the equivalence between Raviart-Thomas mixed methods and certain nonconforming methods. Both the Dirichlet and singular Neumann boundary value problems for second-order elliptic equations are discussed.
