Abstract:
We study the rank-one convex hull of compact sets . We show that if K contains no two matrices whose difference has rank one, and if K contains no four matrices forming a configuration, then the rank-one convex hull is equal to K. Furthermore, we give a simple numerical criterion for testing for configurations.
