Periodic Solutions of Non-Autonomous Second Order Hamiltonian Systems
Fengying Li, Shiqing Zhang, Xiaoxiao Zhao
We try to generalize a result of M. Willem on forced periodic oscillations which required the assumption that the forced potential is periodic on spatial variables. In this paper,…
Periodic Solutions for Circular Restricted 4-body Problems with Newtonian Potentials
Xiaoxiao Zhao, Shiqing Zhang
We study the existence of non-collision periodic solutions with Newtonian potentials for the following planar restricted 4-body problems: Assume that the given positive masses $m_{…
Nonplanar Periodic Solutions for Spatial Restricted 3-Body and 4-Body Problems
Xiaoxiao Zhao, Shiqing Zhang
In this paper, we study the existence of non-planar periodic solutions for the following spatial restricted 3-body and 4-body problems: for , given any masses $m_{1},...,…
Nonplanar Periodic Solutions for Spatial Restricted N+1-Body Problems
Fengying Li, Shiqing Zhang, Xiaoxiao Zhao
We use variational minimizing methods to study spatial restricted N+1-body problems with a zero mass moving on the vertical axis of the moving plane for N equal masses. We prove th…
