六角系统中的固定双键
摘要
六角系统中的一边称为固定双键
如果这个六角系统中的任一个完美匹配都含这条边。本文引入了第二类广义割线的定义
得到了六角系统存在固定双键的充要条件及其固定双键的分布情况。
Abstract
A fixed-double bond is an edge which is in all perfect matching of a hexagonal system
This paper considered fixed-double bonds of hexagonal systems. We obtained a necessary and sufficient condition of hexagonal systems which have fixed double bonds by introducing the concept of second generalized cut segment.
