完全图中Hamilton路和圈的轨道

Orbits of Hamiltonian Paths and Cycles in Complete Graphs

Samuel Herman, Eirini Poimenidou

摘要:

列举了完全图中由Hamilton路和圈诱导的子图的几何等价类。所述类是在表示子图的串集合上的二面体和循环群的某些直积的作用下的轨道。这些轨道的枚举使用伯恩赛德引理。所使用的技巧也为S. W. Golomb和L. R. Welch给出了固定的、规则间隔的顶点上不同的$n$ -顶点的数目,直到旋转和可选的反射。

英文摘要:

We enumerate certain geometric equivalence classes of subgraphs induced by Hamiltonian paths and cycles in complete graphs. Said classes are orbits under the action of certain direct products of dihedral and cyclic groups on sets of strings representing subgraphs. These orbits are enumerated using Burnside's lemma. The technique used also provides an alternative proof of the formulae found by S. W. Golomb and L. R. Welch which give the number of distinct $n$-gons on fixed, regularly spaced vertices up to rotation and optionally reflection.
