Existence and regularity of minimizers of nonconvex integrals with p-q growth
ESAIM: Control, Optimisation and Calculus of Variations, Tome 13 (2007) no. 2, pp. 343-358.

We show that local minimizers of functionals of the form Ω f(Du(x))+g(x,u(x))dx, uu 0 +W 0 1,p (Ω), are locally Lipschitz continuous provided f is a convex function with p-q growth satisfying a condition of qualified convexity at infinity and g is Lipschitz continuous in u. As a consequence of this, we obtain an existence result for a related nonconvex functional.
