Concentration effects of BV gradients have gradient structure

Jan Kristensen, Bogdan Raiţă

We prove that the concentration effects arising from weakly-* convergent sequences of gradients of maps of bounded variation have gradient structure. This is in stark contrast with…

Automatic quasiconvexity of homogeneous isotropic rank-one convex integrands

André Guerra, Jan Kristensen

We consider the class of non-negative rank-one convex isotropic integrands on $R^{n \times n}$ which are also positively $p$ -homogeneous. If $p \leq n = 2$ we prove, condit…
