三角形映射(一种多维连分数)的自然扩展及其来自Young共轭的内部对称性

The Natural Extension for the Triangle Map (a Multi-dimensional Continued Fraction) with An Internal Symmetry from Young Conjugation

Williams College(威廉姆斯学院)

Joe Fox, Thomas Garrity

AI总结:

本文完全描述了所有可能维度下三角形映射的自然扩展,并利用整数分拆的Young共轭发现其具有内部对称性,可将自然扩展细分为四个自然子区域,这一结果对经典连分数情形也是新的。

摘要:

三角形映射(一种多维连分数算法)的自然扩展在所有可能维度下被完整描述。该自然扩展的动机和灵感源于三角形映射最近与整数分拆经典研究的联系。受整数分拆的Young共轭启发,我们证明自然扩展具有内部对称性,并允许将自然扩展细分为四个自然子区域。即使对于经典连分数的自然扩展情形,即经典Gauss映射和经典Farey映射,这似乎也是新的。

英文摘要:

The natural extension of the triangle map (a type of multi-dimensional continued fraction algorithm) is completely described in all possible dimensions. The motivation and inspiration for this natural extension stems from the triangle map's recent link to the classical study of integer partitions. Inspired by Young conjugation for integer partitions, we show that the natural extension has an internal symmetry and allows the natural extension to be subdivided into four natural subdomains. This appears to be new even for the classical case of the natural extension for continued fractions, namely for both the classical Gauss map and the classical Farey map.
