Classification Results for Hyperovals of Generalized Quadrangles [PDF]

open access: yesMathematical Software – ICMS 2020, 2020
A hyperoval of a point-line geometry is a nonempty set of points meeting each line in either 0 or 2 points. We discuss a combination of theoretical and practical techniques that are helpful for classifying hyperovals of generalized quadrangles. These techniques are based on the connection between hyperovals, even sets and pseudo-embeddings of point ...

On the history of generalized quadrangles

open access: yesBulletin of the Belgian Mathematical Society - Simon Stevin, 1994
\textit{S. E. Payne} und \textit{J. A. Thas} [``Finite generalized quadrangles'' (1984; Zbl 0551.05027), Chapter 6] zeigten, daß es genau ein verallgemeinertes Viereck \(Q\) mit \(5\) verschiedenen Punkten auf einer Geraden und 3 verschiedenen Geraden durch einen Punkt gibt.

Topology in generalized quadrangles

open access: yesTopology and Its Applications, 1990
The study of topological generalized quadrangles, in particular 3- dimensional generalized quadrangles, was first taken up by \textit{M. Forst} [Mitt. Math. Semin. Gießen 147, 65-129 (1981; Zbl 0478.51013)]. The authors resume this subject and lay the basis for the study of topological generalized quadrangles in general dimension.

A question of Frohardt on $2$ -groups, skew translation quadrangles of even order and cyclic STGQs

open access: yesForum of Mathematics, Sigma, 2023
We solve a fundamental question posed in Frohardt’s 1988 paper [6] on finite $2$ -groups with Kantor familes, by showing that finite groups K with a Kantor family $(\mathcal {F},\mathcal {F}^*)$ having distinct members $A, B \in \mathcal

Additive two-dimensional splitting schemes for solving 3D suspension transport problems on optimal boundary-adaptive grids with uniform spacing’s in the vertical direction [PDF]

open access: yesE3S Web of Conferences, 2020
The article considers3D matter transport model in dissolved and suspended forms (impurities) in coastal marine systems. The initial boundary value problem numerical solution is carried out on the basis of local2D splitting schemes.

Note on Discovering Doily in PG(2,5)

open access: yesMathematics, 2023
W. L. Edge proved that the internal points of a conic in PG(2,5), together with the collinear triples on the non-secant lines, form the Desargues configuration. M.

COVERS OF GENERALIZED QUADRANGLES [PDF]

open access: yesGlasgow Mathematical Journal, 2018
AbstractWe solve a problem posed by Cardinali and Sastry (Elliptic ovoids and their rosettes in a classical generalized quadrangle of even order.Proc. Indian Acad. Sci. Math. Sci.126(2016), 591–612) about factorization of 2-covers of finite classical generalized quadrangles (GQs). To that end, we develop a general theory of cover factorization for GQs,
