Tee-Seminar: Linde Lambrecht (Universität Gießen): Exploring spherical buildings of type F4 as point-line geometries

Monday, 27.05.2024 14:15 im Raum SR1C

Mathematik und Informatik

In this talk we dive into the world of point-line geometries related to spherical buildings of type F4. These turn out to be parapolar spaces of rank 3 with some extra properties. They differ from the other exceptional spherical buildings by the fact that they are not determined by only a field, but one also needs a quadratic alternative division algebra over this field. This makes them a bit harder to tackle and therefore they are omitted by several authors. After a short introduction, we will discuss some analogs of recent results about other exceptional spherical buildings. In particular, we will discuss subgeometries, domestic collineations and kangaroos
