Abstract: Multidimensional vectorial non-quasiconvex variational problems are relaxed by means of a generalized-Young-functional technique. Selective first-order optimality conditions, having the form of an Euler-Weiestrass condition involving minors, are formulated in a special, rather a model case when the potential has a polyconvex quasiconvexification.
Keywords: relaxed variational problems, Young measures, minors of gradients, optimality conditions, Weierstrass-type maximum principle
