We prove that the quasiconvex envelope of a differentiable function which satisfies natural growth conditions at infinity is a tex2html_wrap_inline9 function. Without the growth conditions the result fails in general. We also obtain results on higher regularity (in the sense of tex2html_wrap_inline11 ) and similar results for other types of envelopes, including polyconvex and rank-1 convex envelopes.
