本文利用动力系统与序理论,证明广义整数分拆集合构成分配格,并刻画了二维 zonotopes 铺砌集合为分配格的不交并,深化了对翻转铺砌行为的理解。

摘要:

本文利用动力系统与序理论研究两类组合对象:广义整数分拆与二维 zonotopes 的铺砌。我们证明了在简单动力学作用下有序的分拆集合具有分配格结构。同样地,我们证明了在简单且经典的动力学作用下有序的 zonotopes 铺砌集合是若干分配格的不交并,并对其进行了描述。我们还讨论了线性整数分拆这一特殊情况,对此存在其他动力系统。这些结果加深了我们对带翻转的 zonotopes 铺砌行为以及涉及分拆的动力系统的理解。

英文摘要:

In this paper, we study two kinds of combinatorial objects, generalized integer partitions and tilings of two dimensional zonotopes, using dynamical systems and order theory. We show that the sets of partitions ordered with a simple dynamics, have the distributive lattice structure. Likewise, we show that the set of tilings of zonotopes, ordered with a simple and classical dynamics, is the disjoint union of distributive lattices which we describe. We also discuss the special case of linear integer partitions, for which other dynamical systems exist. These results give a better understanding of the behaviour of tilings of zonotopes with flips and dynamical systems involving partitions.
