The Multiplicity Problem for Periodic Orbits of Magnetic Flows on the 2-Sphere
Advanced Nonlinear Studies, 2017 We consider magnetic Tonelli Hamiltonian systems on the cotangent bundle of the 2-sphere, where the magnetic form is not necessarily exact. It is known that, on very low and on high energy levels, these systems may have only finitely many periodic orbits.

Homoclinics for strongly indefinite almost periodic second order Hamiltonian systems
Advances in Nonlinear Analysis, 2017 Under certain assumptions, we prove the existence of homoclinic solutions for almost periodic second order Hamiltonian systems in the strongly indefinite case.

On the location of concentration points for singularly perturbed elliptic equations
, 2003 By means of a variational identity of Poho\v{z}aev-Pucci-Serrin type for solutions of class $C^1$ recently obtained, we give some necessary conditions for locating the concentration points for a class of quasi-linear elliptic problems in divergence form.

Infinitely Many Solutions for a Non-homogeneous Differential Inclusion with Lack of Compactness
Advanced Nonlinear Studies, 2019 In this paper, we consider the following class of differential inclusion problems in ℝN{\mathbb{R}^{N}} involving the p(x){p(x)}-Laplacian:

Advances in Nonlinear AnalysisIn this article, we consider the following double critical fractional Schrödinger-Poisson system involving p-Laplacian in R3{{\mathbb{R}}}^{3} of the form: εsp(−Δ)psu+V(x)∣u∣p−2u−ϕ∣u∣ps♯−2u=∣u∣ps*−2u+f(u)inR3,εsp(−Δ)sϕ=∣u∣ps♯inR3,\left\{\begin{array}{l}{\

An Improved Fountain Theorem and Its Application
Advanced Nonlinear Studies, 2017 The main aim of the paper is to prove a fountain theorem without assuming the τ-upper semi-continuity condition on the variational functional. Using this improved fountain theorem, we may deal with more general strongly indefinite elliptic problems with ...

(p,2)-equations asymmetric at both zero and infinity
Advances in Nonlinear Analysis, 2018 We consider a (p,2){(p,2)}-equation, that is, a nonlinear nonhomogeneous elliptic equation driven by the sum of a p-Laplacian and a Laplacian with p>2{p>2}.
