Normalized solutions to Schrödinger equations in the strongly sublinear regime

Jarosław Mederski, Jacopo Schino

We look for solutions to the Schrödinger equation \[ -Δu + λu = g(u) \quad \text{in } \mathbb{R}^N \] coupled with the mass constraint ${\int }_{{\mathbb{R}}^N}|u{|}^{2}dx={\rho }^2$, with $N…
