Abstract

We consider the solution of systems of linear algebraic equations which arise from the finite element discretization of variational problems posed in the Hubert spaces H(div) and H(curl ) in three dimensions. We show that if appropriate finite element spaces and appropriate additive or multiplicative Schwarz smoothers are used, then the multigrid V-cycle is an efficient solver and preconditioner for the discrete operator. All results are uniform with respect to the mesh size, the number of mesh levels, and weights on the two terms in the inner products.
