Compactness of positive radial Solution Sets and corresponding -Mass sets for "Zero Mass" Quasi-linear Schrödinger Equations

Haidong Liu, Yulan Tang, Chengcheng Wu

We study the compactness of two sets of positive radial solutions to ``zero mass'' quasi-linear Schrödinger equation \[ -Δu-uΔ(|u|^2)=g(u) \quad\text{in }\mathbb R^N,\quad N\ge5. \…

Normalized grounded states for a coupled nonlinear schrödinger system on

Chengcheng Wu

We investigate the existence of normalized ground states to the system of coupled Schrödinger equations: \begin{equation}\label{eq:0.1} \begin{cases} -Δu_1 + λ_1 u_1 = μ_1 |u_1|^{p…
