Seminar Archive - 2020

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

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...

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...

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...

Ray Li - UNSW
The goal of this information session is to give some insight to 2nd year students into the process of applying for and successfully obtaining a PhD position. Applying for PhD programs is a complex...

Ian Doust (UNSW), Ray Li (UNSW), Marley Young (University of Cambridge) - As per above
The goal of this information session is to give some insight into the application process for PhD positions in Australia and overseas. Applying for PhD programs is a complex process, from finding the...

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...

Tibor Szabó - Freie Universität Berlin
The Turán number of a (hyper)graph $H$, defined as the maximum number of (hyper)edges in an $H$-free (hyper)graph on a given number of vertices, is a fundamental concept of extremal combinatorics....

Tiangang Cui - Monash University
Characterising intractable high-dimensional random variables is one of the fundamental challenges in stochastic computation. It has broad applications in statistical physics, machine learning,...

Sean Gasiorek - University of Sydney
We give a review of Euclidean and pseudo-Euclidean billiards in the plane and in d-dimensional space. If the billiard table is bounded by confocal quadrics, periodic trajectories can be expressed in...

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...
