Reconfiguration graphs for minimal domination sets

Combinatorics 2024-11-05 v1

Abstract

A dominating set SS in a graph is a subset of vertices such that every vertex is either in SS or adjacent to a vertex in SS. A minimal dominating set MM is a dominating set such that MvM-v is not a dominating set for all vMv \in M. In this paper we introduce a reconfiguration graph R(G)\mathcal{R}(G) for minimal dominating sets under a generalization of the token sliding model. We give some preliminary results which include showing that R(G)\mathcal{R}(G) is connected for trees and split graphs. Additionally we classify all graphs which have R(G)=Kn\mathcal{R}(G) = K_n and R(G)=Kn\mathcal{R}(G) = \overline{K_n} for all nn.
