常曲率空间中$n$ -体问题相对平衡点的延拓

Continuation of relative equilibria in the $n$--body problem to spaces of constant curvature

Abimael Bengochea, Carlos García-Azpeitia, Ernesto Pérez-Chavela, Pablo Roldan

摘要:

证明了平面牛顿$n$ -体问题的所有非退化相对平衡点都可以延拓到常曲率空间$κ$,无论是正曲率还是负曲率,只要这个参数足够小。我们还计算了一些经典的相对平衡曲线空间使用数值延拓。特别地,我们将具有不同质量的拉格朗日三角形构型推广到正曲率空间和负曲率空间。

英文摘要:

We prove that all non-degenerate relative equilibria of the planar Newtonian $n$--body problem can be continued to spaces of constant curvature $κ$, positive or negative, for small enough values of this parameter. We also compute the extension of some classical relative equilibria to curved spaces using numerical continuation. In particular, we extend Lagrange's triangle configuration with different masses to both positive and negative curvature spaces.
