Asymptotic behavior of extremal functions to an inequality involving Hardy potential and critical Sobolev exponent

Benjin Xuan, Jiangchao Wang

Published 2007-01-24Version 1

In this paper, we study the asymptotic behavior of radial extremal functions to an inequality involving Hardy potential and critical Sobolev exponent. Based on the asymptotic behavior at the origin and the infinity, we shall deduce a strict inequality between two best constants. Finally, as an application of this strict inequality, we consider the existence of nontrivial solution of a quasilinear Brezis-Nirenberg type problem with Hardy potential and critical Sobolev exponent.
