The dominating graph of a graph $H$ has as its vertices all dominating sets of $H$, 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 $H$. In this paper we prove that the

The dominating graph of a graph G has as its vertices all dominating sets of G, with an edge between two dominating sets if one can be obtained from the other by adding or deleting a single vertex of G. This is an example of a reconfiguration graph.

The distinguishing chromatic number of a graph, G , is the minimum number of colours required to properly colour the vertices of G so that the only automorphism of G that preserves colours is the identity. There are many classes of graphs for which t

One way of defining an oriented colouring of a directed graph G → is as a homomorphism from G → to a target directed graph H → , and an injective oriented colouring of G → can be defined as a homomorphism from G → to a target directed graph

Let G be a graph and let k be a positive integer. The k -dominating graph of G , denoted by D k ( G ) , has vertices corresponding to the dominating sets of G having cardinality at most k ; two vertices of D k ( G ) are adjacent if and only if the do

Let ?$H$? be a graph and let ?$k \geq \chi (H)$? be an integer. The ?$k$?-colouring graph of ?$H$?, denoted ?$G_k(H)$?, is the graph whose vertex set consists of all proper ?$k$?-vertex-colourings (or simply ?$k$?-colourings) of ?$H$? using colours ?

Given a graph $G$, the $k$-dominating graph of $G$, $D_k(G)$, is defined to be the graph whose vertices correspond to the dominating sets of $G$ that have cardinality at most $k$. Two vertices in $D_k(G)$ are adjacent if and only if the corresponding

We continue the study of small cycle double covers of products of graphs that began in [7], concentrating here on the categorical product and the strong product. Under the assumption that G has an SCDC, we show that G × P m has an SCDC for all m ≠

It has been shown by MacGillivray and Seyffarth (Austral. J. Combin. 24 (2001) 91) that bridgeless line graphs of complete graphs, complete bipartite graphs, and planar graphs have small cycle double covers. In this paper, we extend the result for co
