Strongly regular graphs from hyperbolic quadrics and their maximal cliques

Antonio Cossidente, Jan De Beule, Giuseppe Marino +2

Let $Q^{+} (2 n + 1, q)$ be a hyperbolic quadric of $\PG(2n+1,q)$. Fix a generator $I^$ of the quadric. Define $\cG_n$ as the graph with as vertex set the points of $Q^+(2n+1,q)\setminus…

Segre Varieties and Desarguesian Spreads

Antonio Cossidente, Giuseppe Marino, Francesco Pavese +2

Let $PG (n - 1, q)$ denote the $(n - 1)$ -dimensional projective space over $F_{q}$ . We investigate the intersection of two Desarguesian $(h - 1)$ -spreads of $\mathrm{PG}(kh…
