Large Lagrangian Actions on Elliptical Solutions of 2-Body and 3-Body Problems with Fixed Energies
Ying Lv, Shiqing Zhang
Based on the works of Gordon ([4]) and Zhang-Zhou([8])) on the variational minimizing properties for Keplerian orbits and Lagrangian solutions of Newtonian 2-body and 3-body proble…
Hyperbolic Orbits for a Class of Singular Hamiltonian Systems
Donglun Wu, Shiqing Zhang
The existence of hyperbolic orbits is proved for a class of singular Hamiltonian systems by taking limit for a sequence of periodic solutions which a…
New Periodic Solutions of Singular Hamiltonian Systems with Fixed Energies
Fengying Li, Qingqing Hua, Shiqing Zhang
By using the variational minimizing method with a special constraint and the direct variational minimizing method without constraint, we study second order Hamiltonian systems with…
Twisted Angles for Central Configurations Formed By Two Twisted Regular Polygons
Yu Xiang, Zhang Shiqing
In this paper, we study the necessary conditions and sufficient conditions for the twisted angles of the central configurations formed by two twisted regular polygons, specially, w…
