Existence of least energy positive solutions to Schrödinger systems with mixed competition and cooperation terms: the critical case

Hugo Tavares, Song You

In this paper we investigate the existence of solutions to the following Schrödinger system in the critical case \begin{equation*} -Δu_{i}+λ_{i}u_{i}=u_{i}\sum_{j = 1}^{d}β_{ij}u_{…
