Asymptotic behavior of multiple solutions for quasilinear Schrödinger equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2022
This paper establishes the multiplicity of solutions for a class of quasilinear Schrödinger elliptic equations: \begin{equation*} -\Delta u+V(x)u-\frac{\gamma}{2}\Delta(u^{2})u=f(x,u),\qquad x\in \mathbb{R}^{3}, \end{equation*} where $V(x):\mathbb{R}^3 ...

Existence and concentration of ground state solutions for a critical nonlocal Schr\"odinger equation in $\R^2$ [PDF]

open access: yes, 2016
We study the following singularly perturbed nonlocal Schr\"{o}dinger equation $$ -\vr^2\Delta u +V(x)u =\vr^{\mu-2}\Big[\frac{1}{|x|^{\mu}}\ast F(u)\Big]f(u) \quad \mbox{in} \quad \R^2, $$ where $V(x)$ is a continuous real function on $\R^2$, $F(s)$ is ...

Stability and instability of the quasilinear Gross-Pitaevskii dark solitons*** [PDF]

open access: yesESAIM: Proceedings and Surveys
We study a quasilinear Schrödinger equation with nonzero conditions at infinity. In previous works, we obtained a continuous branch of traveling waves, given by dark solitons indexed by their speed. Neglecting the quasilinear term, one recovers the Gross-

Blow up dynamics for smooth equivariant solutions to the energy critical Schr\"odinger map [PDF]

open access: yes, 2011
We consider the energy critical Schr\"odinger map problem with the 2-sphere target for equivariant initial data of homotopy index $k=1$. We show the existence of a codimension one set of smooth well localized initial data arbitrarily close to the ground ...

Existence of a bound state solution for quasilinear Schrödinger equations

open access: yesAdvances in Nonlinear Analysis, 2017
In this article, we establish the existence of bound state solutions for a class of quasilinear Schrödinger equations whose nonlinear term is asymptotically linear in ℝN{\mathbb{R}^{N}}.

Multiple solutions to a quasilinear Schrödinger equation with Robin boundary condition

open access: yesAIMS Mathematics, 2020
We study a quasilinear Schrödinger equation with Robin boundary condition. Using the variational methods and the truncation techniques, we prove the existence of two positive solutions when the parameter λ is large enough. We also establish the existence

Thence the moment of momentum

open access: yesZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 100, Issue 5, May 2020., 2020
Fifty years have passed since Truesdell's seminal paper on the origin and status of the balance for the moment of momentum was published in ZAMM. It is time to take stock: Important new developments in the theory of generalized continua with internal degrees of freedom and some fascinating fundamental applications need to be pointed out….

Interpolation inequalities and spectral estimates for magnetic operators [PDF]

open access: yes, 2018
We prove magnetic interpolation inequalities and Keller-Lieb-Thir-ring estimates for the principal eigenvalue of magnetic Schr{\"o}dinger operators. We establish explicit upper and lower bounds for the best constants and show by numerical methods that ...
