Title: Hybridization and Postprocessing in Finite Element Exterior Calculus

Abstract: Finite element exterior calculus (FEEC) unifies several families of conforming finite element methods for Laplace-type problems, including the scalar and vector Poisson equations. This talk presents a framework for hybridization of FEEC, which recovers known hybrid methods for the scalar Poisson equation and gives new hybrid methods for the vector Poisson equation using H(curl) elements. We also generalize Stenberg postprocessing, proving new superconvergence estimates.
