Title: Stability of ground states of nonlinear Schrodinger systems Author: Liliana Cely (Univ. of Sao Paulo, Brazil) Abstract: In this article, we study existence and stability of ground states for a system of two coupled nonlinear Schrodinger equations with logarithmic nonlinearity. Moreover, global well-posedness is verified for the Cauchy problem in $H^{1}(\mathbb{R})\times H^{1}(\mathbb{R})$ and in an appropriate Orlicz space. Submitted March 16, 2023.
