Abstract:
We solve a class of isoperimetric problems in the whole spacewith respect to monomial weights.  Our results imply that the optimizers  in some Caffarelli-Kohn-Nirenberg inequalities are radial. Further, they are used to obtain sharp apriori-bounds for solutions to some weighted elliptic BVPs.  \\ This is joint work with A. Alvino, F. Chiacchio and M.R. Posteraro (Napoli).
