Limit cycles bifurcating from the periodic orbits of the weight-homogeneous polynomial centers of weight-degree 3

Autor: Jaume LLibre, Bruno D. Lopes, Jaime R. de Moraes

Publikováno v: Electronic Journal of Differential Equations, Vol 2018, Iss 118,, Pp 1-14 (2018)

In this article we obtain two explicit polynomials, whose simple positive real roots provide the limit cycles which bifurcate from the periodic orbits of a family of polynomial differential centers of order 5, when this family is perturbed inside

Limit cycles bifurcating from the periodic annulus of cubic homogeneous polynomial centers

Autor: Jaume Llibre, Bruno D. Lopes, Jaime R. de Moraes

Publikováno v: Electronic Journal of Differential Equations, Vol 2015, Iss 271,, Pp 1-8 (2015)

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 polynomial differential sys

In this article we deal with non-smooth dynamical systems expressed by a piecewise first order implicit differential equations of the form $$\begin{aligned} \dot{x}=1,\quad \left( \dot{y}\right) ^2=\left\{ \begin{array}{lll} g_1(x,y) \quad \text{ if
