2-Quasiconvexity versus 1-Quasiconvesity Gianni Dal Maso Giovanni Leoni Massimiliano Morini Abstract: In this paper it is shown that a smooth
strictly 2-quasiconvex function with Get the paper in its entirety as |
-growth at infinity, 
,
is the restriction to symmetric matrices of a 
-quasiconvex function
with the same growth. AS a consequence, lower semicontinuity results
for second-order variational problems are deduced as corollaries of
classical first order theorems.
