The mass-mixed case for normalized solutions to NLS equations in dimension two

Daniele Cassani, Ling Huang, Cristina Tarsi +1

\noindent We are concerned with positive normalized solutions $(u,\lambda )\in H^1({\mathbb{R}}^2)\times \mathbb{R}$ to the following semi-linear Schrödinger equations $$ -Δu+λu=f(u), \quad\…
