On cyclicity in discontinuous piecewise linear near-Hamiltonian differential systems with three zones having a saddle in the central one
R. Euzébio, M. Gouveia, D. Novaes +2
In this paper, we study the number of limit cycles that can bifurcate from a periodic annulus of discontinuous planar piecewise linear Hamiltonian differential system with three zo…

Characterization of Non-Deterministic Chaos in Two-Dimensional Non-Smooth Vector Fields
Rodrigo D. Euzébio, Pedro G. Mattos, Régis Varão
Our context is Filippov systems defined on two-dimensional manifolds having a finite number of tangency points. We prove that topological transitivity is a necessary and sufficient…

Lower bounds for the number of limit cycles in a generalized Rayleigh-Liénard oscillator
Rodrigo D. Euzébio, Jaume Llibre, Durval J. Tonon
In this paper a generalized Rayleigh-Liénard oscillator is consider and lower bounds for the number of limit cycles bifurcating from weak focus equilibria and saddle connections ar…
