SUMMARY:Seminar Analysis and Mathematical Physics: Riccardo Tione (MPI Leip
 zig)
DESCRIPTION:This talk concerns critical points $u$ of polyconvex energies o
 f the form $f(X) = g(det(X))$\, where $g$ is (uniformly) convex. It is not
  hard to see that\, if $u$ is smooth\, then $\\det(Du)$ is constant. I wil
 l show that the same result holds for Lipschitz critical points $u$ in the
  plane. I will also discuss how to obtain rigidity for approximate solutio
 ns. This is a joint work with A. Guerra.
