| Abstract: | The purpose of this talk is to review the basic results of finite element exterior calculus (FEEC) and to illustrate how the set up gives rise to
to compatible discretizations of various problems. In particular, we will recall how FEEC, combined with the Bernstein-Gelfand-Gelfand framework, gave new insight into the construction of stable schemes for elasticity methods based on the Hellinger-Reissner variational principle. |
