On the power domination number of de Bruijn and Kautz digraphs
Cyriac Grigorious, Thomas Kalinowski, Joe Ryan +1
Let be a directed graph without parallel arcs, and let be a set of vertices. Let the sequence be defined a…
A lower bound on the zero forcing number
Randy Davila, Thomas Kalinowski, Sudeep Stephen
In this note, we study a dynamic vertex coloring for a graph . In particular, one starts with a certain set of vertices black, and all other vertices white. Then, at each time s…
-supermagic labelings for firecrackers, banana trees and flowers
Rachel Wulan Nirmalasari Wijaya, Andrea Semaničová-Feňovčíková, Joe Ryan +1
A simple graph admits an -covering if every edge in is contained in a subgraph of which is isomorphic to . In this case we say that is -…
Minimum rank and zero forcing number for butterfly networks
Daniela Ferrero, Cyriac Grigorious, Thomas Kalinowski +2
The minimum rank of a simple graph is the smallest possible rank over all symmetric real matrices whose nonzero off-diagonal entries correspond to the edges of . Using t…
