ABSTRACT

We deal with maps u:ΩRnRn minimizing variational integrals Ω[|Du(x)|p+h(detDu(x))]dx, where 2p<n, h:(0,+)[0,+) is convex and blows when detDu0+: limt0+h(t)=+. If such a blow up is a power of |ln(t)|, then we derive regularity for the minimizer u=(u1,,un). We are able also to deal with integrals containing all the minors: Ω[|Du(x)|p+s=2n1|adjs(Du(x))|qs+h(detDu(x))]dx with qs1.
