On a fractional differential equation with infinitely many solutions [PDF]

open access: green, 2012
We present a set of restrictions on the fractional differential equation $x^{(\alpha)}(t)=g(x(t))$, $t\geq0$, where $\alpha\in(0,1)$ and $g(0)=0$, that leads to the existence of an infinity of solutions starting from $x(0)=0$. The operator $x^{(\alpha)}$

Infinitely many periodic solutions for a class of fractional Kirchhoff problems [PDF]

open access: green, 2019
We prove the existence of infinitely many nontrivial weak periodic solutions for a class of fractional Kirchhoff problems driven by a relativistic Schr\"odinger operator with periodic boundary conditions and involving different types of ...

Infinitely many solutions for Schrödinger–Newton equations

open access: yesCommunications in Contemporary Mathematics, 2023
We prove the existence of infinitely many non-radial positive solutions for the Schrödinger–Newton system [Formula: see text] provided that [Formula: see text] has the following behavior at infinity: [Formula: see text] where [Formula: see text] and [Formula: see text] are some positive constants.

A variational approach for mixed elliptic problems involving the p-Laplacian with two parameters

open access: yesBoundary Value Problems, 2022
By exploiting an abstract critical-point result for differentiable and parametric functionals, we show the existence of infinitely many weak solutions for nonlinear elliptic equations with nonhomogeneous boundary conditions. More accurately, we determine

INFINITELY MANY SOLUTIONS FOR A NONLOCAL PROBLEM

open access: yesJournal of Applied Analysis & Computation, 2020
Summary: Consider a class of nonlocal problems \[ \begin{cases} -(a-b\int_{\Omega}|\nabla u|^2dx)\Delta u= f(x,u),\quad &x \in\Omega, \\ u=0, & x \in\partial\Omega, \end{cases} \] where \(a>0\), \(b>0\), \(\Omega\subset \mathbb{R}^N\) is a bounded open domain, \(f:\overline{\Omega} \times \mathbb R \longrightarrow \mathbb R\) is a Carathéodory function.

Infinitely many solutions of degenerate quasilinear Schrödinger equation with general potentials

open access: yesBoundary Value Problems, 2021
In this paper, we study the following quasilinear Schrödinger equation: − div ( a ( x , ∇ u ) ) + V ( x ) | x | − α p ∗ | u | p − 2 u = K ( x ) | x | − α p ∗ f ( x , u ) in  R N , $$ -\operatorname{div}\bigl(a(x,\nabla u)\bigr)+V(x) \vert x \vert ...

Infinitely many solutions for a gauged nonlinear Schrödinger equation with a perturbation

open access: yesNonlinear Analysis, 2021
In this paper, we use the Fountain theorem under the Cerami condition to study the gauged nonlinear Schrödinger equation with a perturbation in R2. Under some appropriate conditions, we obtain the existence of infinitely many high energy solutions for ...

A sequence of positive solutions for sixth-order ordinary nonlinear differential problems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
Infinitely many solutions for a nonlinear sixth-order differential equation are obtained. The variational methods are adopted and an oscillating behaviour on the nonlinear term is required, avoiding any symmetry assumption.
