Planar Semi-quasi Homogeneous Polynomial differential systems with a given degree

Yuzhou Tian, Haihua Liang

This paper study the planar semi-quasi homogeneous polynomial differential systems (short for PSQHPDS), which can be regard as a generalization of semi-homogeneous and of quasi-hom…

Abelian integrals and limit cycles for a class of cubic polynomial vector fields of Lotka-Volterra type with a rational first integral of degree 2

Xiuli Cen, Yulin Zhao, Haihua Liang

In this paper, we study the number of limit cycles which bifurcate from the periodic orbits of cubic polynomial vector fields of Lotka-Volterra type having a rational first integra…
