打结的4-正则图 II:Pachner move的一致应用

Knotted 4-regular graphs II: Consistent application of the Pachner moves

Daniel Cartin

AI总结:

本文研究了圈量子引力中打结图的演化,提出在带有边扭转的框架图上一致应用Pachner move的自然方法,并引入代数对象使任意框架边打结图可用广义辫群表示。

摘要:

在圈量子引力中,打结图演化的一种常见选择是使用从其对偶三角剖分适配到图上的Pachner move。在此我们证明,一致使用这些move的自然方式是在带有边扭转的框架图上进行,其中Pachner move只能在扭转及边所关联的顶点满足特定判据时执行。对于其他扭转,可以引入一个代数对象,使得任何具有框架边的打结图都能用广义辫群来表示。

英文摘要:

A common choice for the evolution of the knotted graphs in loop quantum gravity is to use the Pachner moves, adapted to graphs from their dual triangulations. Here, we show that the natural way to consistently use these moves is on framed graphs with edge twists, where the Pachner moves can only be performed when the twists, and the vertices the edges are incident on, meet certain criteria. For other twists, one can introduce an algebraic object, which allow any knotted graph with framed edges to be written in terms of a generalized braid group.
