### Influence of mean curvature on Mountain-pass solutions for Hardy-Sobolev equations

Hassan Jaber

#### Abstract

Let $\Omega$ be a smooth open domain in $\mathbb{R} ^n$, $n \geq 3$, with $0 \in \partial \Omega$ and $s \in {]}0,2{[}$. Let $2^\star(s) := {2(n-s)}/({n-2})$ be the critical Hardy-Sobolev exponent. Consider the Dirichlet problem that corresponds to the critical and perturbative Hardy-Sobolev equation \begin{aligned}\begin{cases}-\Delta u = {u^{2^\star(s) -1}}/{|x|^s} + h u^{q-1} \quad &\mbox {in } \Omega ,\\u \equiv 0 &\mbox {on } \partial \Omega, \end{cases}\end{aligned} where $q \in {]} 2,2^\star {[}$ with $2^\star := 2^\star (0)$ and $h \in C^0(\overline {\Omega })$, $h \geq 0$, almost everywhere on $\Omega$. In this article, we investigate the influence of perturbation and mean curvature at a boundary singularity on the existence of a positive Mountain pass solution to the above equation.
