Normalized solutions of $L^2$-supercritical NLS equations with periodic potentials

In this paper, we study normalized solutions to the following $L^2$-supercritical nonlinear Schr\"{o}dinger equation with a periodic potential \begin{equation*} \begin{dcases} -\Delta u +V (x)u + \lambda u=\chi_{{\Omega}}(x)f(u)\quad \text{in } \mathbb{R}^N, u>0 \quad \text{in} \ \mathbb{R}^N, \int_{\mathbb{R}^N}\abs{u...
