The Nehari manifold for fractional p-Laplacian system involving concave-convex nonlinearities and sign-changing weight functions

Abstract: In this paper, we consider a fractional p-Laplacian system with both concave-convex nonlinearities and sign-changing weight functions in bounded domains. With the help of the Nehari\ manifold, we prove that the system has at least two nontrivial solutions when the pair of the parameters $(\lambda,\mu)$ belongs to a certain subset of $\mathbb{R}^{n}$
