Ground State Solution for an Autonomous Nonlinear Schrödinger System [PDF]

open access: yesJournal of Function Spaces, 2021
In this paper, we study the following autonomous nonlinear Schrödinger system (discussed in the paper), where λ,μ, and ν are positive parameters; 2∗=2N/N−2 is the critical Sobolev exponent; and f satisfies general subcritical growth conditions.

Existence of Positive Ground State Solutions for Choquard Systems

open access: yesAdvanced Nonlinear Studies, 2020
We study the existence of positive ground state solution for Choquard systems. In the autonomous case, we prove the existence of at least one positive ground state solution by the Pohozaev manifold method and symmetric-decreasing rearrangement arguments.

A global approach to ground state solutions

open access: yesElectronic Journal of Differential Equations, 2008
We study radial solutions of semilinear Laplace equations. We try to understand all solutions of the problem, regardless of the boundary behavior. It turns out that one can study uniqueness or multiplicity properties of ground state solutions by ...

Ground state solutions for p-biharmonic equations

open access: yesElectronic Journal of Differential Equations, 2017
In this article we study the p-biharmonic equation $$ \Delta_p^2u+V(x)|u|^{p-2}u=f(x,u),\quad x\in\mathbb{R}^N, $$ where $\Delta_p^2u=\Delta(|\Delta u|^{p-2}\Delta u)$ is the p-biharmonic operator.
