Limit cycles bifurcating from the quasi-homogeneous polynomial centers of weight-degree 2 under non-smooth perturbations
Shiyou Sui, Yongkang Zhang, Baoyi Li
We investigate the maximum number of limit cycles bifurcating from the period annulus of a family of cubic polynomial differential centers when it is perturbed inside the class of…
Bifurcation of limit cycles from the global center of a class of integrable non-Hamilton system under perturbations of piecewise smooth polynomials
Shiyou Sui, Liqin Zhao
In this paper, we perturb the global center of the planar polynomial vector fields () inside cubic piecewise smooth polynomials…
On the number of limit cycles for generic Lotka-Volterra system and Bogdanov-Takens system under perturbations of piecewise smooth polynomials
Shiyou Sui, Jihua Yang, Liqin Zhao
In this paper, we consider the bifurcation of limit cycles for generic L-V system () and B-T system ($\dot{x}=y,~\dot{y}=-…
On the number of zeros of Abelian integrals for discontinuous quadratic differential systems
Jihua Yang, Liqin Zhao, Shiyou Sui
Applying the Picard-Fuchs equation to the discontinuous differential system, we obtain the upper bounds of the number of zeros for Abelian integrals of four kinds of quadratic diff…
