On least energy solutions for a nonlinear Schrödinger system with $K$-wise interaction

Lorenzo Giaretto, Nicola Soave

In this paper we establish existence and properties of minimal energy solutions for the weakly coupled system $$ \begin{cases} -Δu_i + λ_i u_i = μ_i|u_i|^{Kq-2}u_i + β|u_i|^{q-2}u_…
