Dear Firedrakers, We are hosting Ari Stern (WUSTL) for a talk on Zoom about his work on hybridization of finite element exterior calculus, with Firedrake implementation. This talk is open to all members of the Firedrake community, and the title, abstract and Zoom link (thanks for hosting, Lawrence) is below. The talk is on Tuesday 3rd November, 3pm GMT. all the best --cjc === 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. We also generalize Stenberg postprocessing, proving new superconvergence estimates. Based on joint work with Gerard Awanou, Maurice Fabien, and Johnny Guzman (arXiv:2008.00149). === https://durhamuniversity.zoom.us/j/94677202864?pwd=NGFkZ2QyUkRBREU3NTlnUjhiQ...
