On the cubic perturbations of the symmetric 8-loop Hamiltonian
Iliya D. Iliev, Chengzhi Li, Jiang Yu
We study arbitrary cubic perturbations of the symmetric 8-loop Hamiltonian, which are linear with respect to the small parameter. It is shown that when the first 4 coefficients in…

Centers and limit cycles of a generalized cubic Riccati system
Zhengxin Zhou, Valery G. Romanovski, Jiang Yu
We obtain condition for existence of a center for a cubic planar differential system, which can be considered as a polynomial subfamily of the generalized Riccati system. We also i…
