On a Schrödinger system with shrinking regions of attraction

Mónica Clapp, Alberto Saldaña, Andrzej Szulkin

In this paper we consider a competitive weakly coupled elliptic system in which each species is attracted to a small region and repelled from its complement. In this setting, we es…

Multiple normalized solutions to a system of nonlinear Schrödinger equations

Jarosław Mederski, Andrzej Szulkin

We find a normalized solution $u = (u_{1}, \dots, u_{K})$ to the system of $K$ coupled nonlinear Schrödinger equations \begin{equation*} \left\{ \begin{array}{l} -Δu_i+ λ_i u_i = \sum_{j=…
