Description

An instructional research workshop

This event has ended. However, if you would like access to the recordings, please contact Administration with the contact details on the Contacts page.

 
This event will be held online. Please note registration is required to attend this conference. 
 

Recently there has been substantial interest in using ideas from p-adic and motivic integration to study the interplay between geometric and arithmetic aspects of moduli spaces such as character varieties, Higgs bundles and quiver varieties. The geometric invariants associated with these moduli spaces are governed by topological quantum field theories. Arithmetic methods can be used to study these invariants by relating them to the representation theory of finite groups of Lie type and point counting over finite fields. These techniques reveal an intimate relation to the theory of symmetric polynomials and have found applications in mirror symmetry and the Langlands program. 

This instructional workshop is focused on the above circle of ideas and is directed primarily at postgraduate students and early career researchers in Australia and New Zealand. The aim is to bring together experts working in these research areas and create an opportunity for fruitful interactions.

Program

The event will feature four mini-courses:

1.   Arithmetic geometry and representation varieties (Masoud Kamgarpour, UQ)
2.   Topological quantum field theory and character varieties (Pedram Hekmati, Auckland)
3.   Representation zeta functions (Uri Onn, ANU)
4.   Moduli space of Higgs bundles (David Baraglia, Adelaide)

Research talks

This workshop will also consist of 3 research talks.

Marina Logares  (Universidad Complutense de Madrid)

Michael Groechenig (University of Toronto)

Nir Avni (Northwestern University)

Michele Zordan (Imperial College)
