Positive ground states for a system of Schrödinger equations with critically growing nonlinearities



We study the following problem
$$\begin{aligned} {\left\{ \begin{array}{ll} -\Delta u = \lambda u + u^{2^*-2} v &{}\quad \hbox {in }\quad \Omega ,\\ -\Delta v= \mu v^{2^*-1} + u^{2^*-1} &{}\quad \hbox {in }\quad \Omega ,\\ u> 0,v> 0 &{}\quad \hbox {in }\quad \Omega ,\\ u=v=0 &{}\quad \hbox {on }\quad \partial \Omega , \end{array}\right. } \end{aligned}$$
where \(\Omega \) is a bounded domain of \(\mathbb {R}^N\), \(N\ge 4\), \(2^*=2N/(N-2)\), \(\lambda \in \mathbb {R}\) and \(\mu \ge 0\) and we obtain existence and nonexistence results, depending on the value of the parameters \(\lambda \) and \(\mu \).

We would like to thank Giusi Vaira for her valuable comments concerning the problem in case \(N\ge 6\).
