DATE: Thursday, 18 November PLACE: Eng E206 at 12:10 SPEAKER: Rieuwert Blok (CSU) TITLE: Title: Lie geometries ABSTRACT: I will define and discuss Lie geometries and some related concepts and show how they tie to fundamental concepts in the theory of Lie algebras, groups with BN-pair and buildings. I will also discuss some new and old results on these geometries showing how geometric and algebraic properties of these geometries are interconnected.
