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...
