Solvability of a second-order Hamiltonian system with impulsive effects
, 2013 In this paper, a class of second-order Hamiltonian systems with impulsive effects are considered. By using critical point theory, we obtain some existence theorems of solutions for the nonlinear impulsive problem.

A note on a global invertibility of mappings on $R^{n}$
, 2015 We provide sufficient conditions for a mapping $f:R^{n}\rightarrow R^{n}$ to be a global diffeomorphism in case it is strictly (Hadamard) differentiable.

Multiple solutions for the quasilinear Choquard equation with Berestycki-Lions-type nonlinearities
Advances in Nonlinear AnalysisIn this article, we study the following quasilinear equation with nonlocal nonlinearity −Δu−κuΔ(u2)+λu=(∣x∣−μ*F(u))f(u),inRN,-\Delta u-\kappa u\Delta \left({u}^{2})+\lambda u=\left({| x| }^{-\mu }* F\left(u))f\left(u),\hspace{1em}\hspace{0.1em}\text{in ...

The E-Cohomological Conley Index, Cup-Lengths and the Arnold Conjecture on T2n
Advanced Nonlinear Studies, 2019 We show that the E-cohomological Conley index, that was introduced by the first author recently, has a natural module structure. This yields a new cup-length and a lower bound for the number of critical points of functionals on Hilbert spaces.

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.
