Liouville theorems and symmetry of positive solutions for partially confined nonlinear Schrödinger equations

Zhijie Chen, Youjun Wang, Jianjun Zhang +1

This paper studies positive solutions to the stationary nonlinear Schrödinger equation with a partial harmonic confinement: $$-Δu + \big( x_1^2 + \cdots + x_d^2 \big) u + λu = g(u)…

Uniqueness of radial solutions for -Laplacian equations in low dimensions

Patrizia Pucci, Jianjun Zhang, Xuexiu Zhong

This paper extends the uniqueness results of Serrin and Tang [\textit{Indiana Univ. Math. J.}, 49 (2000), pp. 897--923] to the low-dimensional case with . We c…

Multiple normalized solutions for two coupled Gross-Pitaevskii equations with attractive interactions and mass constriants

Zhang Jianjun, Zhong Xuexiu, Zhou Jinfang

We are concerned with the following system of two coupled time-independent Gross-Pitaevskii equations $$ \begin{cases} -Δu+λ_1 u=μ_1|u|^{p-2}u+να|u|^{α-2}|v|^βu ~\hbox{in}~…

Serrin-type Overdetermination in Scaling Limits: Sharp Existence and Asymptotic Behavior of Quasi-linear Schrödinger Energy Ground States

Louis Jeanjean, Jianjun Zhang, Xuexiu Zhong

This paper establishes optimal existence results and limiting profiles for energy ground states of the quasi-linear Schrödinger equation $$ -Δu - Δ(|u|^{2})u + λu = |u|^{p-2}u…
