  • In this paper, using the mountain pass theorem we obtain a positive solution to the fractional Laplacian problem

    $ \begin{equation*} \label{eq: main problem} \begin{cases} (-\Delta)^su = g(x)(u-k)_{+}^{q-1}+u^{\frac{n+2s}{n-2s}}& \rm{in}\ \,\Omega,\\ u>0& \rm{in}\ \,\Omega,\\ u = 0& \rm{on}\ \,\partial\Omega, \end{cases} \end{equation*} $

    where $ \Omega\subset {\mathbb R}^{n} $ is a bounded smooth domain, $ 0 < s < 1, 2\leq q < {2n}/(n-2s) $ and $ k\in(0, \infty) $ is an arbitrary number. The function $ g:{\Omega}\to {\mathbb R} $ is a nonnegative continuous function satisfying some integrability condition.
