On the power domination number of de Bruijn and Kautz digraphs

Cyriac Grigorious, Thomas Kalinowski, Joe Ryan +1

Let $G = (V, A)$ be a directed graph without parallel arcs, and let $S \subseteq V$ be a set of vertices. Let the sequence $S = S_{0} \subseteq S_{1} \subseteq S_{2} \subseteq \dots$ be defined a…

$H$ -supermagic labelings for firecrackers, banana trees and flowers

Rachel Wulan Nirmalasari Wijaya, Andrea Semaničová-Feňovčíková, Joe Ryan +1

A simple graph $G = (V, E)$ admits an $H$ -covering if every edge in $E$ is contained in a subgraph $H^{'} = (V^{'}, E^{'})$ of $G$ which is isomorphic to $H$ . In this case we say that $G$ is $H$ -…
