Our regular seminar program covers a broad range of topics from applied mathematics, pure mathematics and statistics. All staff and students are welcome. This page has a complete list of past seminars and a list restricted by year can be accessed via the left-hand menu.

Victoria Gu - UNSW Sydney
An elliptic curve over a field k is a smooth projective curve of genus 1 with a distinguished point O. With Riemann-Roch theorem and assuming that char(K) $\neq$ 2,3 ,  every elliptic curve can be...

Martin Helmer - Australian National University
In this talk I will consider two invariants associated to pairs of strata X , Y in an analytic stratification of some ambient complex projective variety W. The main result states that if the closure...

Martino Lupini - Victoria University of Wellington, New Zealand
The problem of classifying solenoids, their complements in S^3, and continuous maps on them was posed by Borsuk and Eilenberg in 1936. At the time, it stimulated substantial advances in algebraic...

Ramiro Lafuente - The University of Queensland, Australia
In this talk I will introduce the Ricci flow evolution equation for Riemannian metrics on a smooth manifold, without assuming any previous knowledge on differential geometry. Then I will discuss...

Cyril Houdayer - University of Paris-Saclay, Orsay
I will talk about a recent joint work with Remi Boutonnet in which we show that for higher rank lattices (e.g. SL(3, Z)), the left regular representation is weakly contained in any weakly mixing...

Sean Gasiorek - University of Sydney
Mathematical billiards has been a playground for various topics within geometry and dynamical systems for the last 100 years. In this talk, we give an introduction to mathematical billiards and...

Dave Robertson - University of New England
A group G acting faithfully by homeomorphisms of the Cantor set is called piecewise full if any homeomorphism assembled piecewise from elements of G is itself an element of G. I will discuss when...

Paul Lessard - Macquarie University
We'll begin with a revisionist history of model category theory (we'll imagine that, in place of homological algebra, the notion had its origin in category theory). Using this apocryphal premise, we'...

Nelson Chen - UNSW
A combinatorial reciprocity theorem relates two classes of combinatorial objects via their counting functions. We shall explore the chromatic polynomial, which counts the number of proper n-...

Ray Li - UNSW
A famous result of Northcott's states that the set of preperiodic points of a rational function in a number field has finite size. Recently there has been interest in the arithmetic structure of...
