Buffa A. Remarks on the discretization of some non-coercive operator with applications to Maxwell equations with jumping coefficients. Technical report ercim.cnr.ian//2003-1326, 2003.
We aim at providing a framework for the analysis of convergence for the Galerkin approximation for a class of non-coercive problems . We provide a sufficient condition on the finite element space for the convergence and optimality of the Galerkin scheme. The theory is then applied to two problems in electromagnetism.
Subject Non-coercive operators, finite elements, Maxwell equations
