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…
Stacked Central Configurations for Newtonian N+4-Body Problems
Furong Zhao, Shiqing Zhang
In this paper,we study spatial central configurations where N bodies are at the vertices of a regular N-gon and the other 4 bodies are symmetrically located on the straight lin…
