Infinitely many solutions via variational-hemivariational inequalities under Neumann boundary conditions

Electronic Journal of Differential Equations, 2016
In this article, we study the variational-hemivariational inequalities with Neumann boundary condition. Using a nonsmooth critical point theorem, we prove the existence of infinitely many solutions for boundary-value problems.

A unified treatment using critical point methods of the existence of multiple solutions for superlinear and sublinear neumann problems

, 2011
In this paper we present a framework which permits the unified treatment of the existence of multiple solutions for superlinear and sublinear Neumann problems. Using critical point theory, truncation techniques, the method of upper-lower solutions, Morse

Variational-hemivariational inequalities with nonhomogeneous Neumann boundary condition

Le Matematiche, 2010
The aim of this paper is the study of variational-hemivariational inequalities with nonhomogeneous Neumann boundary condition. Sufficient conditions for the existence of a whole sequence of solutions which is either unbounded or converges to zero are ...

A deformation theorem in the noncompact nonsmooth setting and its applications

Electronic Journal of Differential Equations, 2001
We build a deformation for a continuous functional defined on a Banach space and invariant with respect to an isometric action of a noncompact group. Under these assumptions the Palais-Smale condition does not hold.

Non-smooth extension of a three critical points theorem by Ricceri with an application to p(x)-Laplacian differential inclusions

Electronic Journal of Differential Equations, 2015
We extend a smooth Ricceri three critical-points theorem to a non-smooth case. Our approach is based on the non-smooth analysis. As an application, we obtain the existence of at least three critical points for a p(x)-Laplacian differential inclusion.

Multiplicity of solutions for some degenerate quasilinear elliptic equations

Electronic Journal of Differential Equations, 2009
We show the existence of infinitely many solutions for a symmetric quasilinear problem whose principal part is degenerate.

Existence of solutions for discontinuous p(x)-Laplacian problems with critical exponents

Electronic Journal of Differential Equations, 2012
In this article, we study the existence of solutions to the problem $$displaylines{ -hbox{div}(|abla u|^{p(x)-2}abla u) =lambda |u|^{p^{*}(x)-2}u + f(u)quad x in Omega ,cr u = 0 quad x in partialOmega, }$$ where $Omega$ is a smooth bounded domain ...

Multiple positive solutions for Schrödinger-Poisson system with singularity on the Heisenberg group

Journal of Inequalities and Applications
In this work, we study the following Schrödinger-Poisson system { − Δ H u + μ ϕ u = λ u − γ , in  Ω , − Δ H ϕ = u 2 , in  Ω , u > 0 , in  Ω , u = ϕ = 0 , on  ∂ Ω , $$ \textstyle\begin{cases} -\Delta _{H}u+\mu \phi u=\lambda u^{-\gamma}, &\text{in ...
