Buildings, surfaces and quaternions

Presented by: 
Alina Vdovina Newcastle University
Date: 
Tuesday 30th May 2017 - 10:00 to 11:00
Venue: 
INI Seminar Room 2
Abstract: 
Buildings are exciting objects which have geometric, algebraic and number theoretical aspects. We will give elementary constructions of several classes of buildings as universal covers of finite complexes. Then (as a geometric application) we will show a connection of our results with Gromov's surface subgroup question and (as an arithmetic application) we will give explicit examples of quaternionic lattices.
