Abstract:
We analyze the semiconvex hulls of the subset K in symmetric matrices given by that was first considered by Dacorogna & Tanteri [Commun. in PDEs 2001]. We obtain explicit formulae for the polyconvex, the quasiconvex, and the rank-one convex hull for and show in particular that the quasiconvex and the polyconvex hull are different if strict inequality holds. For we obtain a closed form for the polyconvex and the rank-one convex hull.
