规则五角形中的长短周期台球轨迹

Long and Short Periodic Billiard Trajectories in the Regular Pentagon

Samuel Everett, Vanessa Lin, Aidan Mager

摘要:

在规则五边形台球桌上的任何周期方向上,存在两个组合不同的台球路径,其中一个比另一个长。对于每一个周期性方向,麦克马伦问是否可以确定通过给定点的周期性轨迹是长的,短的,还是鞍形连接。在本文中,我们提出了一个算法解决这个问题的轨迹从五角形的中点。

英文摘要:

In any periodic direction on the regular pentagon billiard table, there exists two combinatorially different billiard paths, with one longer than the other. For each periodic direction, McMullen asked if one could determine whether the periodic trajectory through a given point is long, short, or a saddle connection. In this paper we present an algorithm resolving this question for trajectories emanating from the midpoints of the pentagon.
