Necessary and sufficient conditions of well-posedness
of a mixed formulation of symmetric problems
Abstract
We consider a standard mixed formulation of a symmetric
problem
Au+B*p=0
B(u-g)=0
We derive necessary and sufficient conditions of wellposedness.
As an application, we consider a Hellinger-Reissner formulation of nonhomogeneous
Lame equations for media with (almost) rigid inclusions. The (almost) incompressible
case is covered as well.
