Keywords:
polyconvex envelope; rank one convex envelope; lower semicontinuous functional; quasiconvex functional; coercive integral functional; radially symmetric function of Kohn-Strang type
Summary:
We study polyconvex envelopes of a class of functions related to the function of Kohn and Strang introduced in . We present an example of a function of this class for which the polyconvex envelope may be computed explicitly and we also point out some general features of the problem.
