Link Download full text Abstract Stemming from the characterization of the static condensation procedure for mixed hybridized methods introduced in [9],[10], in this paper we use Helmholtz decompositions to obtain a substructuring of the local mapping problems, in order to end up with simpler systems of reduced size. This procedure is effective especially when dealing with high degree or variable degree approximations. Moreover, we extend the variational characterization of static condensation to more general saddle-point formulations. Two relevant examples of hybridized mixed methods are considered, namely, the classical Galerkin Dual-Mixed Hybridized scheme and the Discontinuous Petrov-Galerkin (DPG) scheme of [7].
