(Spin) Topological Quantum Field Theory

Thomas Wasserman
(Oxford)
Abstract

This'll be a nice and slow paced introduction to topological quantum field theory in general, and 1-2-3 dimensional theories in particular. If time permits I will explain the spin version of these and their connection to physics. There will be lots of pictures. 

Congratulations to Dr Catherine Wilkins from Oxford Mathematics who has won a MPLS (Mathematical Physical and Life Sciences Division) award for teaching excellence. Oxford Teaching Awards are given either to individuals or to teams as a public acknowledgement of excellence in teaching and learning.

Growth of homology torsion in residually finite groups

Nikolay Nikolov
(Oxford)
Abstract

I will report on recent progress towards understanding the growth of the torsion of the homology of subgroups of finite index in a given residually finite group G.

The cases I will consider are when G is amenable (joint work with P, Kropholler and A. Kar) and when G is right angled (joint work with M. Abert and T. Gelander).
