Bi-center conditions and bifurcation of limit cycles in a class of -equivariant cubic switching systems with two nilpotent points
Ting Chen, Feng Li, Yun Tian +1
In this paper, we generalize the Poincaré-Lyapunov method for systems with linear type centers to study nilpotent centers in switching polynomial systems and use it to investigate…

Nilpotent center conditions in cubic switching polynomial Liénard systems by higher-order analysis
Ting Chen, Feng Li, Pei Yu
The aim of this paper is to investigate two classical problems related to nilpotent center conditions and bifurcation of limit cycles in switching polynomial systems. Due to the di…
