Nonlocal critical Kirchhoff problems in high dimension

We study the nonlocal critical Kirchhoff problem $$\displaylines{ -\Big(a+b\int_\Omega |\nabla u|^2dx\Big)\Delta u =|u|^{2^*-2}u +\lambda f(x,u), \quad \text{in } \Omega,\cr u=0, \quad \text{on } \partial\Omega, }$$ where $\Omega$ is a bounded smooth domain in $R^N$, $N>4$, $a,b>0$, $\lamb...

Description
Summary:We study the nonlocal critical Kirchhoff problem $$\displaylines{ -\Big(a+b\int_\Omega |\nabla u|^2dx\Big)\Delta u =|u|^{2^*-2}u +\lambda f(x,u), \quad \text{in } \Omega,\cr u=0, \quad \text{on } \partial\Omega, }$$ where $\Omega$ is a bounded smooth domain in $R^N$, $N>4$, $a,b>0$, $\lambda\in R$, $2^*:=\frac{2N}{N-2}$ is the critical exponent for the Sobolev embedding, and $f:\Omega\times R\to R$ is a Caratheodory function with subcritical growth. We establish the existence of global minimizers for the energy functional associated to this problem. In particular, we improve a recent result proved by Faraci and Silva [3] under more strict conditions on the nonlinearity f and under additional conditions on a and b.
