摘要
In this paper, we study the multiplicity results of positive solutions for a semi-linear elliptic system involving both concave convex and critical growth terms. With the help of the Nehari manifold and the Lusternik Schnirelmann category, we investigate how the coefficient h(x) of the critical nonlinearity affects the number of positive solutions of that problem and get a relationship between the number of positive solutions and the topology of the global maximum set of h.
