New lower bound for the number of critical periods for planar polynomial systems
Xiuli Cen
In this paper, we construct two classes of planar polynomial Hamiltonian systems having a center at the origin, and obtain the lower bounds for the number of critical periods for t…

On the Stability of Symmetric Periodic Orbits of the Elliptic Sitnikov Problem
Xiuli Cen, Xuhua Cheng, Zaitang Huang +1
Motivated by the recent works on the stability of symmetric periodic orbits of the elliptic Sitnikov problem, for time-periodic Newtonian equations with symmetries, we will study s…
