Abstract

This paper is concerned with the existence of multiple positive‎
‎solutions for a quasilinear elliptic system involving concave-convex‎
‎nonlinearities‎
‎and sign-changing weight functions‎. ‎With the help of the Nehari manifold and Palais-Smale condition‎,
‎we prove that the system has at least two nontrivial positive‎
‎solutions‎, ‎when the pair of parameters $(\lambda,\mu)$ belongs to a certain subset of $\mathbb{R}^2$‎.
