Four-body Central Configurations with Adjacent Equal Masses
Yiyang Deng, Bingyu Li, Shiqing Zhang
For any convex non-collinear central configuration of the planar Newtonian 4-body problem with adjacent equal masses , with equal lengths for the two diagonals…
A Note on Homoclinic Orbits for Second Order Hamiltonian Systems
Bingyu Li, Fengying Li, Donglun Wu +1
In this paper, we study the existence for the homoclinic orbits for the second order Hamiltonian systems. Under suitable conditions on the potential , we apply the direct method…
Periodic Solutions for -Body-Type Problems
Fengying Li, Shiqing Zhang
We consider non-autonomous -body-type problems with strong force type potentials at the origin and sub-quadratic growth at infinity, and using Ljusternik-Schnirelmann theory, we…
Central Configurations Formed By Two Twisted Regular Polygons
Xiang Yu, Shiqing Zhang
In this paper, we study the necessary conditions and sufficient conditions for the central configurations formed by two twisted regular polygons (one N-regular polygon and one L-re…
6-Body Central Configurations Formed by Two Isosceles Triangles
Furong Zhao, Shiqing Zhang
In this paper,we show the existence of a class of 6-body central configurations with two isosceles triangles; which are congruent to each other and keep some distance.We also study…
Hyperbolic Orbits for a Class of Singular Hamiltonian Systems with Repulsive Potentials
Donglun Wu, Shiqing Zhang
The existence of hyperbolic orbits is proved for a class of singular Hamiltonian systems with repulsive potentials by taking limit for a sequence of periodic solutions which are th…
