will speak on

Tits' buildings as combinatorial objects

at 3pm Friday 28 November in Mathematics Lecture Room 1.

Abstract:

Buildings were invented in the 1960s by the Belgian-French mathematician Jacques Tits. They are a useful tool to "visualise" algebraic groups (such as classical and exceptional Lie groups). The simplest examples are the projective spaces. Other examples include polar spaces, generalised polygons, infinite trees. I will give a general introduction to the concept of buildings, from several points of view, with special emphasis on the chamber system point of view, which is very combinatorial. I will then illustrate how that combinatorial structure can be used to show results that apply to many different types of buildings at once.
