On the classification of low degree ovoids of $Q^{+} (5, q)$

Daniele Bartoli, Nicola Durante, Giovanni Giuseppe Grimaldi

Ovoids of the Klein quadric $Q^{+} (5, q)$ of $PG (5, q)$ have been studied in the last 40 year, also because of their connection with spreads of $PG (3, q)$ and hence tr…

On $m$ -ovoids of $Q^{+} (7, q)$ with $q$ odd

Sam Adriaensen, Jan De Beule, Giovanni Giuseppe Grimaldi +1

In this paper, we provide a construction of $(q + 1)$ -ovoids of the hyperbolic quadric $Q^{+} (7, q)$ , $q$ an odd prime power, by glueing $(q + 1) /2$ -ovoids of the elliptic quadric $Q^-(5,…
