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…
