Achievable multiplicity partitions in the inverse eigenvalue problem of a graph

Mohammad Adm, Shaun Fallat, Karen Meagher +3

Associated to a graph is a set of all real-valued symmetric matrices whose off-diagonal entries are nonzero precisely when the corresponding vertices of the gr…

Properties of a -analogue of zero forcing

Steve Butler, Craig Erickson, Shaun Fallat +6

Zero forcing is a combinatorial game played on a graph where the goal is to start with all vertices unfilled and to change them to filled at minimal cost. In the original variation…

The Cop Number of the One-Cop-Moves Game on Planar Graphs

Ziyuan Gao, Boting Yang

Cops and robbers is a vertex-pursuit game played on graphs. In the classical cops-and-robbers game, a set of cops and a robber occupy the vertices of the graph and move alternately…

Ovoids of Generalized Quadrangles of Order and Delsarte Cocliques in Related Strongly Regular Graphs

Mohammad Adm, Ryan Bergen, Ferdinand Ihringer +4

We investigate strongly regular graphs for which Hoffman's ratio bound and Cvetcović's inertia bound are equal. This means that , where is the number of ve…

Infection in Hypergraphs

Ryan Bergen, Shaun Fallat, Adam Gorr +5

In this paper a new parameter for hypergraphs called hypergraph infection is defined. This concept generalizes zero forcing in graphs to hypergraphs. The exact value of the infecti…

Compressed Cliques Graphs, Clique Coverings and Positive Zero Forcing

Shaun Fallat, Karen Meagher, Abolghasem Soltani +1

Zero forcing parameters, associated with graphs, have been studied for over a decade, and have gained popularity as the number of related applications grows. In particular, it is w…

On the Complexity of the Positive Semidefinite Zero Forcing Number

Shaun Fallat, Karen Meagher, Boting Yang

The positive zero forcing number of a graph is a graph parameter that arises from a non-traditional type of graph colouring, and is related to a more conventional version of zero f…

Algorithms for Cut Problems on Trees

Iyad Kanj, Guohui Lin, Tian Liu +7

We study the {\sc multicut on trees} and the {\sc generalized multiway Cut on trees} problems. For the {\sc multicut on trees} problem, we present a parameterized algorithm that ru…
