Cyclicity of Rigid Centers on Center Manifolds of Three-dimensional systems
Claudio Pessoa, Lucas Queiroz, Jarne D. Ribeiro
We work with polynomial three-dimensional rigid differential systems. Using the Lyapunov constants, we obtain lower bounds for the cyclicity of the known rigid centers on their cen…
Analytic Nilpotent Centers on Center Manifolds
Claudio Pessoa, Lucas Queiroz
Consider analytical three-dimensional differential systems having a singular point at the origin such that its linear part is for some . The res…

Limit Cycles Bifurcating from a Periodic Annulus in Discontinuous Planar Piecewise Linear Hamiltonian differential System with Three Zones
Claudio Pessoa, Ronisio Ribeiro
In this paper, we study the number of limit cycles that can bifurcating from a periodic annulus in discontinuous planar piecewise linear Hamiltonian differential system with three…
Limit Cycles from Planar Piecewise Linear Hamiltonian differential Systems with Two or Three Zones
C. Pessoa, R. Ribeiro
In this paper, we study the existence of limit cycles in continuous and discontinuous planar piecewise linear Hamiltonian differential systems with two or three zones separated by…
Monodromy and Dulac's Problem for Piecewise analytical planar vector fields
Claudio Buzzi, João Carlos Medrado, Claudio Pessoa
Consider an analytical function having as its regular value, a switching manifold and a piecewise analytical vector fi…
