Abstract

We study the elliptic system \begincases -Δu1 - κ1u1 = μ1|u1|p-2u1 + λα|u1|α-2|u2|βu1,
-Δu2 - κ2u2 = μ2|u2|p-2u2 + λβ|u1|α|u2|β-2u2,
u1,u2∈ D1,20(Ω), \endcases where Ω is a bounded domain in ℝN, N≥ 3, κ12∈ℝ, μ12,λ>0, α,β>1, and α+ β= p≤ 2^*:=(2N)/(N-2). For p∈ (2,2^*) we establish the existence of a ground state and of a prescribed number of fully nontrivial solutions to this system for λ sufficiently large. If p=2^* and κ12>0 we establish the existence of a ground state for λ sufficiently large if, either N≥5, or N=4 and neither κ1 nor κ2 are Dirichlet eigenvalues of -Δ in Ω.
