Abstract: | In this paper we investigate the following Kirchhoff type elliptic boundary value problem involving a critical nonlinearity: $$\left\{\begin{array}{ll}-(a+b\int_{\Omega}|\nabla u|^2dx)\Delta u=\mu g(x,u)+u^5, u>0& \text{in }\Omega,\\ u=0& \text{on }\partial \Omega,\end{array}\right. {\rm {(K1)}}$$ here \({\Omega \subset \mathbb{R}^3}\) is a bounded domain with smooth boundary \({\partial \Omega, a,b \geq 0}\) and a + b > 0. Under several conditions on \({g \in C(\overline{\Omega} \times \mathbb{R}, \mathbb{R})}\) and \({\mu \in \mathbb{R}}\) , we prove the existence and nonexistence of solutions of (K1). This is some extension of a part of Brezis–Nirenberg’s result in 1983. |
