有向图的挠率与路复形

Torsion of digraphs and path complexes

Alexander Grigor'yan, Yong Lin, Shing-Tung Yau

摘要:

利用作者在\cite{Grigoryan-Lin-Muranov-Yau2013, Grigoryan-Lin-Muranov-Yau2014, Grigoryan-Lin-Muranov-Yau2015, Grigoryan-Lin-Muranov-Yau2020}中引入的路同调论,定义了有向图的Reidemeister挠和解析挠的概念.本文证明了两个挠率概念的同一性,并给出了有向图的笛卡儿积和并的挠率公式。

英文摘要:

We define the notions of Reidemeister torsion and analytic torsion for directed graphs by means of the path homology theory introduced by the authors in \cite{Grigoryan-Lin-Muranov-Yau2013, Grigoryan-Lin-Muranov-Yau2014, Grigoryan-Lin-Muranov-Yau2015, Grigoryan-Lin-Muranov-Yau2020}. We prove the identity of the two notions of torsions as well as obtain formulas for torsions of Cartesian products and joins of digraphs.
