%0 Journal Article %T Lp estimates and asymptotic behavior for finite energy solutions of extremals to Hardy-Sobolev inequalities %A Dimiter Vassilev %J Mathematics %D 2006 %I arXiv %X Motivated by the equation satisfied by the extremals of certain Hardy-Sobolev type inequalities, we show sharp $L^q$ regularity for finite energy solutions of p-laplace equations involving critical exponents and possible singularity on a sub-space of $\mathbb{R}^n$, which imply asymptotic behavior of the solutions at infinity. In addition, we find the best constant and extremals in the case of the considered $L^2$ Hardy-Sobolev inequality. %U http://arxiv.org/abs/math/0601662v3
