Let 0/R n be open, u : 0 ร R m and thus the gradient matrix Du # R m\_n . We let E/R m\_n be compact and denote by RcoE and PcoE the rank one convex and polyconvex hull of E, respectively. We show that if RcoE=PcoE (and two other hypotheses, named the segment property and the extreme points property
