Normalized clustering peak solutions for Schrödinger equations with general nonlinearities

Chengxiang Zhang, Xu Zhang

We are concerned with the normalized $\ell$-peak solutions to the nonlinear Schrödinger equation \[ -\varepsilon^2Δv+V(x)v=f(v)+λv,\quad \int_{\mathbb{R}^N}v^2 =α\varepsilon^N. \]…
