如何听到台球桌的形状

How to hear the shape of a billiard table

Aaron Calderon, Solly Coles, Diana Davis, Justin Lanier, Andre Oliveira

摘要:

多边形台球桌的反弹谱是与台球桌上的台球轨迹相对应的边缘标签的所有双无穷序列的集合。我们给出了从多边形台球桌的反弹谱重建其边缘标签的循环排序和其角度的大小的方法。我们还表明,它是不可能的,以重建一个多边形台球桌的确切形状从任何有限的收集有限字从它的反弹谱。

英文摘要:

The bounce spectrum of a polygonal billiard table is the collection of all bi-infinite sequences of edge labels corresponding to billiard trajectories on the table. We give methods for reconstructing from the bounce spectrum of a polygonal billiard table both the cyclic ordering of its edge labels and the sizes of its angles. We also show that it is impossible to reconstruct the exact shape of a polygonal billiard table from any finite collection of finite words from its bounce spectrum.
