Existence of solutions for Hardy-Sobolev-Maz'ya systems
Electronic journal of differential equations, Tome 2012 (2012)
The main goal of this article is to investigate the existence of solutions for the Hardy-Sobolev-Maz'ya system

$\displaylines{ -\Delta u-\lambda \frac{u}{|y|^2}=\frac{|v|^{p_t-1}}{|y|^t}v,\quad \hbox{in }\Omega,\cr -\Delta v-\lambda \frac{v}{|y|^2}=\frac{|u|^{p_s-1}}{|y|^s}u,\quad \hbox{in }\Omega,\cr u=v=0,\quad \hbox{on }\partial \Omega }$

where $0\in\Omega$ which is a bounded, open and smooth subset of $\mathbb{R}^k\times \mathbb{R}^{N-k}, 2\leq k$. The non-existence of classical positive solutions is obtained by a variational identity and the existence result by a linking theorem.
