不可定向曲面中图的二聚体
Dimers on graphs in non-orientable surfaces
摘要:
本文的主要结果是二聚体模型的配分函数在图G上的一个Pfronan公式嵌入在一个封闭的,可能是不可定向的表面S。该公式适用于计算目的,并且它是使用纯几何方法获得的。证明中的关键步骤是G上的某些定向与S上的pin^-结构集之间的对应。这推广(并简化)了以前文献[2]的结果。
英文摘要:
The main result of this paper is a Pfaffian formula for the partition function of the dimer model on a graph G embedded in a closed, possibly non-orientable surface S. This formula is suitable for computational purposes, and it is obtained using purely geometrical methods. The key step in the proof consists of a correspondence between some orientations on G and the set of pin^- structures on S. This generalizes (and simplifies) the results of a previous paper [2].
