Abstract

In this paper we consider the following elliptic system in R3 equation presented are non-negative real functions defined on R3 so that lim equation presented and lim equation presented When K(x) ≡ K∞ and a(x) ≡ a∞ we have already proved the existence of a radial ground state of the above system. Here, by using a new version of the moving plane method, we show that all positive solutions of the above system with K(x) ≡ K∞ and a(x) ≡ a∞ are radially symmetric and the linearized operator around a radial ground state is also non-degenerate. Using these results we further prove, under additional assumptions on K(x) and a(x), but not requiring any symmetry property on them, the existence of a positive solution for the system.
