Concentration-Compactness Principle for generalized Moser-Trudinger inequalities: characterization of the non-compactness in the radial case

Abstrakt

We extend a result concerning sequential weak continuity of the Moser functional to the case of a nontrivial weak limit and the borderlineexponent from the Concentration-Compactness Alternative.
