In this paper we focus on existence and symmetry properties of solutions to the cubic Schrödinger system -δui + λiui = ∑j=1d βijuj2ui in Ω ⊂ RN, i = 1, . . . d where d ≥ 2, λi, βii > 0, βij = βji ∈ R for j ≠ i, N = 2, 3. The underlying domain Ω is either bounded or the whole space, and ui ∈ H01(Ω) or ui ∈ Hrad1(RN) respectively. We establish new existence and symmetry results for least energy positive solutions in the case of mixed cooperation and competition coefficients, as well as in the purely cooperative case.

Abstract
In this paper we focus on existence and symmetry properties of solutions to the cubic Schrödinger system -δui + λiui = ∑j=1d βijuj2ui in Ω ⊂ RN, i = 1, . . . d where d ≥ 2, λi, βii > 0, βij = βji ∈ R for j ≠ i, N = 2, 3. The underlying domain Ω is either bounded or the whole space, and ui ∈ H01(Ω) or ui ∈ Hrad1(RN) respectively. We establish new existence and symmetry results for least energy positive solutions in the case of mixed cooperation and competition coefficients, as well as in the purely cooperative case.File in questo prodotto:
