Dynamics of a generalized Rayleigh system
Maíra Duran Baldissera, Jaume Llibre, Regilene Oliveira
Consider the first order differential system given by \begin{equation*} \begin{array}{l} \dot{x}= y, \qquad \dot{y}= -x+a(1-y^{2n})y, \end{array} \end{equation*} where is a rea…

Limit cycles for two classes of control piecewise linear differential systems
J. Llibre, R. D. S. Oliveira, C. A. B. Rodrigues
We study the bifurcation of limit cycles from the periodic orbits of --dimensional linear centers when they are perturbed inside classes of continuous and dis…

On the structural stability of planar quasihomogeneous polynomial vector fields
Regilene D. S. Oliveira, Yulin Zhao
Denote by the space of all planar -quasihomogeneous vector fields of degree endowed with the coefficient topology. In this paper we characterize the set $Ω_{pq…
