Hefetz, Mütze, and Schwartz conjectured that every connected undirected graph admits an antimagic orientation (Hefetz et al., 2010). In this paper we support the analogous question for distance magic labeling. Let Γ be an Abelian group of order n. A directed Γ-distance magic labeling of an oriented graph ⃗ G = (V, A) of order n is a bijection ⃗ l : V → Γ with the property that there is a magic constant µ ∈ Γ such that for every x ∈ V (G) w(x) = ∑ y∈N + (x) ⃗ l(y) − ∑ y∈N − (x) ⃗ l(y) = µ. In this paper we provide an infinite family of odd regular graphs possessing an orientable Z n-distance magic labeling. Our results refer to lexicographic product of graphs. We also present a family of odd regular graphs that are not orientable Z n-distance magic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
