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…
