A new cycle structure theorem for Hamiltonian graphs
-
摘要: 设
$ G $ 是一个$ n $ 阶图, 若对于每一个$ k\;(3\leqslant k\leqslant n) $ , 图$ G $ 都含有$ k $ -圈, 则称图$ G $ 为泛圈图. 泛圈图是圈理论研究中的重要课题. 研究得到了Hamilton圈上两个不相邻的点在圈上的距离是3的泛圈性结果.Abstract: An$ n $ -vertex graph is called pancyclic if it contains a cycle of length$ k $ for every$ k\;(3\leqslant k\leqslant n) $ . Pancyclic graphs are an important topic in cycle theory. In this paper, we demonstrate pancyclicity by showing that the distance between two non-adjacent vertices on a Hamiltonian cycle is 3.-
Key words:
- Hamiltonian graph /
- pancyclic graph /
