Projective Two-Weight Sets of Denniston Type
Stefaan De Winter
We construct two-weight sets in PG, with the same weights as those that would arise from the blow-up of a maximal -arc in PG. The construction is of…
Weak isometries of the Boolean cube
S. De Winter, M. Korb
Consider the metric space consisting of the -dimensional Boolean cube equipped with the Hamming distance. A weak isometry of is a permutation of $\ma…
Automorphisms of strongly regular graphs
S. De Winter, E. Kamischke, Z. Wang
In this article we generalize a theorem of Benson for generalized quadrangles to strongly regular graphs and directed strongly regular graphs. The main result provides numerical re…
Linear representations of subgeometries
Stefaan De Winter, Sara Rottey, Geertrui Van de Voorde
The linear representation of a point set in a hyperplane of is a point-line geometry embedded in this projective space. In t…
A criterion concerning Singer groups of generalized quadrangles, and construction of uniform lattices in -buildings
Stefaan De Winter, Koen Thas
We describe a simple criterion to construct Singer groups of Payne-derived generalized quadrangles, yielding, as a corollary, a classification of Singer groups of the classical Pay…
Characterizations of finite classical polar spaces by intersection numbers with hyperplanes and speces of codimension 2
Stefaan De Winter, Jeroen Schillewaert
In this article we show that non-singular quadrics and non-singular Hermitian varieties are completely characterized by their intersection numbers with respect to hyperplanes and s…
