| Title: | Hybridization of Discontinuous Galerkin FEM for Second Order Elliptic Problems |
| Time: | 3:00-4:00 pm |
| Place: | Blocker 628 |
In the last several years B. Cockburn and J. Gopalakrishnan introduced
a new hybridization technique for mixed FEM for second
order elliptic equations. The main ideas of this technique combined with
the the technique of lifting operators from the discontinuous Galerkin
approximations led to a unified hybridization technique for
discontinuous Galerkin (DG), mixed, nonconforming, and conforming
finite element
approximations of second order elliptic problems.
In the talk we shall discuss this general hybridization framework for second
order elliptic problems, which is characterized by
(1) the finite element spaces of the local solutions,
(2) the numerical traces of the solution and the flux, and
(3) the space of the Lagrange multiplier.
