Bifurcation of limit cycles from a non-smooth perturbation of a two-dimensional isochronous cylinder
(2016-06-01)
Detect the birth of limit cycles in non-smooth vector fields is a very important matter into the recent theory of dynamical systems and applied sciences. The goal of this paper is to study the bifurcation of limit cycles ...
Hyperbolic periodic orbits from the bifurcation of a four-dimensional nonlinear center

Limit cycles of some polynomial differential systems in dimension 2, 3 and 4, via averaging theory

Ciclos limite e suas configurações em Campos de Vetores Polinomiais Planares
(Universidade Estadual Paulista (Unesp), 2017-02-23)
Estudamos dois critérios sobre a não existência ou existência e unicidade de ciclos limites para campos vetoriais planares. Aplicamos esses critérios em algumas famílias de campos vetoriais quadráticos e cúbicos, além de ...
Limit cycles for singular perturbation problems via inverse integrating factor
(2008-12-01)
In this paper singularly perturbed vector fields Xε defined in ℝ2 are discussed. The main results use the solutions of the linear partial differential equation XεV = div(Xε)V to give conditions for the existence of limit ...

Limit Cycles for a Class of Continuous and Discontinuous Cubic Polynomial Differential Systems
(Springer, 2014-04-01)
We study the maximum number of limit cycles that bifurcate from the periodic solutions of the family of isochronous cubic polynomial centers(x) over dot = y(-1 + 2 alpha x + 2 beta x(2)), (y) over dot = x + alpha(y(2) - ...
On the number of limit cycles in discontinuous piecewise linear differential systems with two pieces separated by a straight line
(Elsevier B.V., 2015-04-01)
In this paper we study the maximum number N of limit cycles that can exhibit a planar piecewise linear differential system formed by two pieces separated by a straight line. More precisely, we prove that this maximum number ...
LIMIT CYCLES BIFURCATING FROM THE PERIODIC ANNULUS OF CUBIC HOMOGENEOUS POLYNOMIAL CENTERS
(Texas State Univ, 2015-10-21)
We obtain an explicit polynomial whose simple positive real roots provide the limit cycles which bifurcate from the periodic orbits of any cubic homogeneous polynomial center when it is perturbed inside the class of all ...
