Enriched finite element subspaces for dual–dual mixed formulations in fluid mechanics and elasticity (Elsevier, 2005)[Abstract] In this paper we unify the derivation of finite element subspaces guaranteeing unique solvability and stability of the Galerkin schemes for a new class of dual-mixed variational formulations. The approach, which ...
