弯曲四体问题的矩形轨道

Rectangular orbits of the curved 4-body problem

Florin Diacu, Brendan Thorn

摘要:

我们考虑常曲率空间中的四体问题,研究球面和双曲矩形解的存在性,即球面和双曲球面上的等角四边形运动。我们专注于相对平衡(保持恒定相互距离的轨道)和旋转脉冲器(旋转和改变大小,但保持等角的配置)。我们证明了,当这样的轨道存在时,它们必然是球面或双曲平方,即等角等边四边形。

英文摘要:

We consider the 4-body problem in spaces of constant curvature and study the existence of spherical and hyperbolic rectangular solutions, i.e. equiangular quadrilateral motions on spheres and hyperbolic spheres. We focus on relative equilibria (orbits that maintain constant mutual distances) and rotopulsators (configurations that rotate and change size, but preserve equiangularity). We prove that when such orbits exist, they are necessarily spherical or hyperbolic squares, i.e. equiangular equilateral quadrilaterals.
