## The numbers of positive solutions by the Lusternik-Schnirelmann category for a quasilinear elliptic system critical with Hardy terms.(English)Zbl 1475.35148

Summary: In this paper, we study the quasilinear elliptic system with Sobolev critical exponent involving both concave-convex and Hardy terms in bounded domains. By employing the technique introduced by V. Benci and G. Cerami [Arch. Ration. Mech. Anal. 114, No. 1, 79–93 (1991; Zbl 0727.35055)], we obtain at least $$\operatorname{cat}(\Omega) + 1$$ distinct positive solutions.
