Arcs, Caps and Generalisations in a Finite Projective Space
J. W. P. Hirschfeld, J. A. Thas
Arcs and caps are fundamental structures in finite projective spaces. They can be generalised. Here, a survey is given of some important results on these objects, in particular on…
Generalized Quadrangles Of Order . IV. Translations, Moufang And Fong-Seitz
Joseph A. Thas
In the period 1994-1999 Thas wrote a series of three papers on generalized quadrangles of order . In this Part IV we classify all finite translation generalized quadrangl…
Covers of generalized quadrangles, 2. Kantor-Knuth covers and embedded ovoids
J. A. Thas, K. Thas
In this paper, which is a sequel to \cite{part1}, we proceed with our study of covers and decomposition laws for geometries related to generalized quadrangles. In particular, we ob…
On k-caps in PG(n, q), with q even and n \geq 4
Joseph A. Thas
Let , be the maximum size of k for which there exists a complete k-cap in PG(n, q). In this paper the known bounds for , q even and $q \ge…
