The quasi principal rank characteristic sequence

Shaun M. Fallat, Xavier Martínez-Rivera

A minor of a matrix is quasi-principal if it is a principal or an almost-principal minor. The quasi principal rank characteristic sequence (qpr-sequence) of an $n \times n$ symmetri…

Ovoids of Generalized Quadrangles of Order $(q, q^{2} - q)$ 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 $v e^{-} = m^{-} (e^{-} - k)$ , where $v$ is the number of ve…
