Infinitely many solutions to perturbed elliptic equations

open access: yesJournal of Functional Analysis, 2005
AbstractA new version of perturbation theory is developed which produces infinitely many sign-changing critical points for uneven functionals. The abstract result is applied to the following elliptic equations with a Hardy potential and a perturbation from symmetry:-Δu-μu|x|2=f(x,u)+p(x,u) in Ω,u=0 on ∂Ωand-Δu=|u|q-2|x|su+p(x,u) in Ω,u=0 on ∂Ω,where ...

Two-breather solutions for the class I infinitely extended nonlinear Schrodinger equation and their special cases [PDF]

open access: yesNonlinear Dynamics 98, 1(2019) 245-255, 2020
We derive the two-breather solution of the class I infinitely extended nonlinear Schrodinger equation (NLSE). We present a general form of this multi-parameter solution that includes infinitely many free parameters of the equation and free parameters of the two breather components.

Infinitely many normalized solutions for a quasilinear Schrodinger equation [PDF]

open access: yesarXiv, 2023
In this paper, we are concerned with a quasilinear Schrodinger equation with well-known Berestycki--Lions nonliearity. The existence of infinitely many normalized solutions is obtained via a minimax argument.

A potential system with infinitely many critical periods [PDF]

open access: yesarXiv, 2022
In this paper, we propose an analytical non-polynomial potential system which has infinitely many critical periodic orbits in phase plane. By showing the existence of infinitely many $2\pi-$ periodic solutions, the proof bases on variational methods and the properties of Bessel function.

The Lagrangian Conley Conjecture

open access: yes, 2010
We prove a Lagrangian analogue of the Conley conjecture: given a 1-periodic Tonelli Lagrangian with global flow on a closed configuration space, the associated Euler-Lagrange system has infinitely many periodic solutions.
