A criterion concerning Singer groups of generalized quadrangles, and construction of uniform lattices in $C_{2}$ -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…

Hyperfield extensions, characteristic one and the Connes-Consani plane connection

Koen Thas

Inspired by a recent paper of Alain Connes and Catherina Consani which connects the geometric theory surrounding the elusive field with one element to sharply transitive group acti…

The Weyl functor - Introduction to Absolute Arithmetic

Koen Thas

Starting from an ancient observation of Tits concerning the interpretation of symmetric groups as Chevalley groups over a (non-existing) field having only one element, we describe…
