Remarks on a Sobolev-Hardy inequality

Analysis of PDEs 2007-05-23 v3

Abstract

We compute the optimal constant for a generalized Hardy-Sobolev inequality, and using the product of two symmetrizations we present an elementary proof of the symmetries of some optimal functions. This inequality was motivated by a nonlinear elliptic equation arising in astrophysics.
