Existence and Limiting Profiles of Normalized Travelling Wave Solutions for the Pseudo-Relativistic Schrödinger Equation with Logarithmic Nonlinearity

Pietro d'Avenia, Qihan He, Alessio Pomponio +1

We study the existence and asymptotic behaviour of normalized solutions to the following pseudo-relativistic Schrödinger equation with logarithmic nonlinearity \[ (\sqrt{-Δ+m^2 }-m…

Infinitely many multi-peaks solutions for a nonlinear Hartree system

Qihan He, Qingfang Wang

In this paper, we study the following nonlinear Hartree system: $- Δ u_{i} + V_{i} (x) u_{i} = μ_{i} ϕ_{u_{i}} u_{i} + \sum_{j \neq = i} β_{ij} ϕ_{u_{j}} u_{i}$ for $x \in R^{3}$ , with $u_i\in H^1(\math…

Multiple positive solutions with prescribed masses for a coupled Schrödinger system: mass mixed and Sobolev critical coupled case

Qing Guo, Qihan He, Wei Shuai +1

The aim of this paper is to establish multiple positive normalized solutions $(u, v, λ_{1}, λ_{2}) \in H^{1} (R^{N}, R^{2}) \times R^{2}$ to the following coupled Schröding…
