A note on Poincaré- and Friedrichs-type inequalities
Abstract
We introduce a simple criterion to check coercivity of bilinear forms on subspaces of Hilbert-spaces. The presented criterion allows to derive many standard and non-standard variants of Poincaré- and Friedrichs-type inequalities with very little effort.
