Properties of a $q$ -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…

On the almost-principal minors of a symmetric matrix

Shaun M. Fallat, Xavier Martínez-Rivera

The almost-principal rank characteristic sequence (apr-sequence) of an $n \times n$ symmetric matrix is introduced, which is defined to be the string $a_{1} a_{2} \dots a_{n - 1}$ , where…
