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…

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 $G$ . In particular, one starts with a certain set of vertices black, and all other vertices white. Then, at each time s…

Minimum rank and zero forcing number for butterfly networks

Daniela Ferrero, Cyriac Grigorious, Thomas Kalinowski +2

The minimum rank of a simple graph $G$ is the smallest possible rank over all symmetric real matrices $A$ whose nonzero off-diagonal entries correspond to the edges of $G$ . Using t…
