A New Infinite Family of Hemisystems of the Hermitian Surface

John Bamberg, Melissa Lee, Koji Momihara +1

In this paper, we construct an infinite family of hemisystems of the Hermitian surface $H (3, q^{2})$ . In particular, we show that for every odd prime power $q$ congruent to $…

A family of $m$ -ovoids of parabolic quadrics

Tao Feng, Koji Momihara, Qing Xiang

We construct a family of $\frac{( q - 1 )}{2}$ -ovoids of $Q (4, q)$ , the parabolic quadric of $PG (4, q)$ , for $q \equiv 3 (mod 4)$ . The existence of $\frac{( q - 1 )}{2}$ -ovoids of $Q(…
