Sign changing solutions of p-fractional equations with concave-convex nonlinearities

Abstract

In this article we study the existence of sign changing solution of the following p-fractional problem with concave-critical nonlinearities: \begin{eqnarray*} (-Δ)^s_pu &=& μ|u|^{q-1}u + |u|^{p^*_s-2}u \quad\mbox{in}\quad Ω, u&=&0\quad\mbox{in}\quad\mathbb{R}^N\setminusΩ, \end{eqnarray*} where $s\in (0,1)$ and $p\ge 2$ are fixed parameters, $0<q<p-1$, $\mu \in {\mathbb{R}}^{+}$ and $p_s^{\ast }=\frac{Np}{N-ps}$. $\Omega$ is an open, bounded domain in ${\mathbb{R}}^N$ with smooth boundary with $N>ps$ .
