Abstract:
We prove that rank-(n-1) convexity does not imply formula11-quasiconvexity (i.e., quasiconvexity with respect to divergence free fields) in the space of formula13 matrices for m>n, by adapting the well-known Sverák's counterexample to the solenoidal setting. On the other hand, we also remark that rank-(n-1) convexity and formula11-quasiconvexity turn out to be equivalent in the space of formula21 diagonal matrices. This follows by a generalization of Müller's work.
