Abstract

In this paper, we consider the following Robin problem \begin{equation}\label{eq:0.1} \left\{ \begin{array}{ll} -\-\Delta u=|x|^\alpha u^p \ & x\in \Omega, \\ \displaystyle u>0, & x \in \Omega,\\ \displaystyle \frac{\partial u}{\partial \nu} +\beta u=0 & x\in \partial \Omega,\\ \end{array} \right. \end{equation} where $\Omega$ is the unit ball in $\mathbb{R}^N$ centered at the origin, with $N\geq 3$. $p>1, \,\alpha>0, \beta>0$ and $\nu$ is the unit outward vector normal to $\partial\Omega$. We prove that the above problem has no solution when $\beta$ is small enough. We also obtain existence results and we analysis the symmetry breaking of the ground state solutions. 10.1017/S0004972713000476
