Hamilton Paths in Dominating Graphs of Trees and Cycles

Combinatorics 2022-02-08 v2

Abstract

The dominating graph of a graph HH has as its vertices all dominating sets of HH, with an edge between two dominating sets if one can be obtained from the other by the addition or deletion of a single vertex of HH. In this paper we prove that the dominating graph of any tree has a Hamilton path. We also show how a result about binary strings leads to a proof that the dominating graph of a cycle on nn vertices has a Hamilton path if and only if n≢0(mod4)n\not\equiv 0 \pmod 4.
