Relative $m$ -ovoids of elliptic quadrics

A. Cossidente, F. Pavese

Let $Q^{-} (2 n + 1, q)$ be an elliptic quadric of $PG (2 n + 1, q)$ . A relative $m$ -ovoid of $Q^{-} (2 n + 1, q)$ (with respect to a parablic section ${\cal Q} := {\cal Q}(2n,q)…

Hyperovals of $H (3, q^{2})$ when $q$ is even

Antonio Cossidente, Oliver H. King, Giuseppe Marino

For even $q$ , a group $G$ isomorphic to $P S L (2, q)$ stabilizes a Baer conic inside a symplectic subquadrangle $W (3, q)$ of $H (3, q^{2})$ . In this paper the action of $G$ o…
