(eng): In the scalar n-dimensional situation, the extreme points in the set of certain gradient Lp-Young measures are studied. For n=1, such Young measures must be composed from Diracs, while for n>1 there are non-Dirac extreme points among them, for n>2, some are even weakly* continuous. This is used to construct nontrivial examples of nonexistence of solutions of the minimization-type variational problems.
