## On a class of nonlocal elliptic problems with critical growth.(English)Zbl 1198.35281

Summary: This paper is concerned with the existence of positive solutions to the class of nonlocal boundary value problems of Kirchhoff type
$-\left[M\left(\int_{\Omega} |\nabla u|^2\, dx \right)\right]\Delta u= \lambda f(x,u)+ u^5 \;\text{ in }\Omega,\quad u(x)>0\;\text{ in }\Omega \quad\text{and}\quad u=0\;\text{ on }\partial \Omega ,$
where $$\Omega\subset\mathbb R^N$$, for $$N=1,2$$ and 3, is a bounded smooth domain, $$M$$ and $$f$$ are continuous functions and $$\lambda$$ is a positive parameter. Our approach is based on the variational method.
