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.

A note on a global invertibility of mappings on Rn
, 2016 We provide sufficient conditions for a mapping ƒ: Rn → Rn to be a global diffeomorphism in case ƒ need not be continuously differentiable. Instead it is assumed to be strictly (Hadamard-like) and Frechet differentiable.

A pathological example in nonlinear spectral theory
Advances in Nonlinear Analysis, 2017 We construct an open set Ω⊂ℝN{\Omega\subset\mathbb{R}^{N}} on which an eigenvalue problem for the p-Laplacian has no isolated first eigenvalue and the spectrum is not discrete.

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.
