Hermitian indicator sets

A Cossidente, G Lunardon, G Marino, O Polverino - 2007 - degruyter.com
Indicator sets arising from symplectic line-spreads of a 3-dimensional projective space are
characterized. Moreover, locally Hermitian ovoids of a Hermitian surface (3, q 2) are studied …

[HTML][HTML] Parameters for which the Griesmer bound is not sharp

A Klein, K Metsch - Discrete mathematics, 2007 - Elsevier
We prove for a large class of parameters t and r that a multiset of at most tθd-k+ rθd-k-2
points in PG (d, q) that blocks every k-dimensional subspace at least t times must contain a …

On Ovoids of the Generalized Quadrangle

B De Bruyn - Annals of Combinatorics, 2021 - Springer
We construct examples and families of locally Hermitian ovoids of the generalized
quadrangle H (3, q 2). We also obtain a computer classification of all locally Hermitian …

Spreads of PG(3, q) and ovoids of polar spaces

L Bader, G Marino, O Polverino, R Trombetti - 2007 - degruyter.com
To any spread 𝒮 of PG (3, q) corresponds a family of locally hermitian ovoids of the
Hermitian surface H (3, q 2), and conversely; if in addition 𝒮 is a semifield spread, then each …

Special sets of the Hermitian surface and indicator sets

A Cossidente, G Marino… - Journal of Combinatorial …, 2008 - Wiley Online Library
An interesting connection between special sets of the Hermitian surface of PG (3, q2), q
odd,(after Shult 13) and indicator sets of line‐spreads of the three‐dimensional projective …

On semiclassical translation ovoids of H (3, q²)

B De Bruyn - RESULTS IN MATHEMATICS, 2022 - biblio.ugent.be
Two semiclassical translation ovoids of the generalized quadrangle H (3, q (2)) are
isomorphic when their associated semiclassical indicator sets are equivalent. We study in …

[PDF][PDF] Some results on spreads and ovoids

L Bader - Rend. Mat. Appl.(7), 2010 - core.ac.uk
We survey some results on ovoids and spreads of finite polar spaces, focusing on the ovoids
of H (3, q2) arising from spreads of PG (3, q) via indicator sets and Shult embedding, and on …
