A new proof on quasilinear Schrödinger equations with prescribed mass and combined nonlinearities

Jianhua Chen, Jijiang Sun, Chenggui Yuan +1

In this work, we study the quasilinear Schrödinger equation \begin{equation*} \aligned -Δu-Δ(u^2)u=|u|^{p-2}u+|u|^{q-2}u+λu,\,\, x\in\R^N, \endaligned \end{equation*} under the mas…
