The Nehari manifold method for discrete fractional p-Laplacian equations [PDF]

open access: yesAdvances in Difference Equations, 2020
The aim of this paper is to investigate the multiplicity of homoclinic solutions for a discrete fractional difference equation. First, we give a variational framework to a discrete fractional p-Laplacian equation.

Nehari manifold for degenerate logistic parabolic equations

open access: yesElectronic Journal of Differential Equations
In this article we analyze the behavior of solutions to a degenerate logistic equation with a nonlinear term $b(x)f(u)$ where the weight function $b$ is non-positive.

A borderline analysis of the Nehari manifold method for concave-convex system

open access: yesTopological Methods in Nonlinear Analysis
The aim of this paper is to obtain an existence and multiplicity result for a strongly coupled concave-convex system for an {\it optimal} choice of involved real parameters via the Nehari manifold method. In the paper, we have obtained the parametric region which is optimal in the sense that the constraint minimization idea based on the Nehari ...

On the existence of ground states of an equation of Schrödinger–Poisson–Slater type

open access: yesComptes Rendus. Mathématique, 2021
We study the existence of ground states of a Schrödinger–Poisson–Slater type equation with pure power nonlinearity. By carrying out the constrained minimization on a special manifold, which is a combination of the Pohozaev manifold and Nehari manifold ...

Existence and multiplicity of solutions to fractional p-Laplacian systems with concave–convex nonlinearities [PDF]

open access: yesBulletin of Mathematical Sciences, 2020
This paper is concerned with a fractional p-Laplacian system with both concave–convex nonlinearities. The existence and multiplicity results of positive solutions are obtained by variational methods and the Nehari manifold.

Existence of Positive Ground State Solutions for Fractional Choquard Systems in Subcritical and Critical Cases

open access: yesMathematics, 2023
We investigate a class of fractional linearly coupled Choquard systems. For the subcritical case and all critical cases, we prove the existence, nonexistence and symmetry of positive ground state solutions of systems, by using the Nehari manifold method,

NON-NEHARI MANIFOLD METHOD FOR SUPERLINEAR SCHRÖDINGER EQUATION [PDF]

open access: yesTaiwanese Journal of Mathematics, 2014
We consider the boundary value problem \begin{equation} \label{(0.1)} \left\{ \begin{array}{ll} -\triangle u+V(x)u=f(x, u), \ \ \ \  & x\in \Omega,\\ u=0, \ \ \ \ & x\in \partial\Omega, \end{array} \right. \end{equation} where $ \Omega \subset \mathbb R^N$ be a bounded domain, $\inf_{\Omega}V(x)>-\infty$, $f$ is a superlinear, subcritical ...
