关于三维镶嵌空间的连通性

On the connectivity of spaces of three-dimensional tilings

Juliana Freire, Caroline J. Klivans, Pedro H. Milet, Nicolau C. Saldanha

摘要:

本文研究了三维有边和无边的离散流形的多米诺拼接,包括欧几里得空间和三维环面的子集。特别是,我们感兴趣的连接组件的空间的平铺这些地区下的本地移动。在第三和第四作者的工作基础上,我们允许两种可能的局部移动,翻转和trit。这些移动被认为是相对于两个拓扑不变量,扭曲和通量。我们的主要结果证明,直到细化:两个tilings连接的翻转和trits当且仅当他们有相同的流量。当且仅当两个平铺具有相同的通量和扭曲时,它们仅通过翻转连接。

英文摘要:

We consider domino tilings of three-dimensional cubiculated manifolds with or without boundary, including subsets of Euclidean space and three-dimensional tori. In particular, we are interested in the connected components of the space of tilings of such regions under local moves. Building on the work of the third and fourth authors, we allow two possible local moves, the flip and trit. These moves are considered with respect to two topological invariants, the twist and flux. Our main result proves that, up to refinement: Two tilings are connected by flips and trits if and only if they have the same flux. Two tilings are connected by flips alone if and only if they have the same flux and twist.
