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…

Infinitely many new solutions for a nonlinear coupled Schrödinger system

Qingfang Wang, Mingxue Zhai

We revisit the following nonlinear Schrödinger system \begin{align*}\begin{cases} -ε^{2}Δu +P(x) u= μ_1 u^3 +βuv^2, &~\text{in}\;\mathbb {R}^3,\\ -ε^{2}Δv+Q(x) v= μ_2 v^3 +βu^2v, &…

Positive and sign-changing solutions for the nonlinear Schrödinger systems with synchronization and separation

Qingfang Wang, Wenju Wu

In this paper, we consider the following nonlinear Schrödinger system: - $Δ$ u+P(x)u= $μ_{1}$ $u^{3}$ + $β$ u $v^{2}$ , x $\in$ $R^{3}$ ,\\ - $Δ$ v+Q(x)v= $μ_{2}$ $v^{3}$ + $β$ $u^{2}$ v, x $\in$ $R^{3}$ , whe…

Infinitely many solutions with simultaneous synchronized and segregated components for nonlinear Schrödinger systems

Qingfang Wang, Dong Ye

In this paper, we consider the following nonlinear Schrödinger system in $R^{3}$ : \begin{align*} -Δu_j +P_j(x) u=μ_j u_j^3+\sum\limits_{i=1,i\neq j}^Nβ_{ij}u_i^2u_j, \end{align*} whe…
