Automorphism groups of a graph and a vertex-deleted subgraph
Stephen G. Hartke, Hannah Kolb, Jared Nishikawa +1
Understanding the structure of a graph along with the structure of its subgraphs is important for several problems in graph theory. Two examples are the Reconstruction Conjecture a…
Fire containment in grids of dimension three and higher
Mike Develin, Stephen G. Hartke
We consider a deterministic discrete-time model of fire spread introduced by Hartnell [1995] and the problem of minimizing the number of burnt vertices when deploying a limited num…
A general notion of visiblity graphs
Mike Develin, Stephen Hartke, David Petrie Moulton
We define a natural class of graphs by generalizing prior notions of visibility, allowing the representing regions and sightlines to be arbitrary. We consider mainly the case of co…
