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.

Anne Thomas - University of Sydney
The notion of divergence of geodesics was introduced by Gromov in the 1980s as a way of quantifying how fast a pair of geodesic rays in a space move away from each other.  Gersten then used this idea...

Anna Romanov - University of Sydney
Whittaker modules are certain representations of Lie algebras which were first studied by Kostant for their relationship to the Whittaker equation in number theory. From a representation-theoretic...

Yusra Naqvi - University of Sydney
Many simplicial complexes which are important from a combinatorial, geometric or representation-theoretic perspective have enormous symmetry groups. Associated to the action of a group $G$ on a...

Leonard Scott - University of Virginia
This talk is based on  joint work with Brian Parshall and Jie Du, in progress.  I will give some of the history and framework leading to the main conjecture we had made, asserting the existence of a...

Mircea Voineagu - University of New South Wales
Bredon motivic cohomology is a cohomology theory for equivariant algebraic varieties over a field of characteristic zero. We discuss Bredon motivic cohomology in the context of equivariant motivic...

Alexander Jason Dunn - University of Illinois
Let   $f(q):=1+\sum_{n=1}^\infty \frac{q^{n^2}}{(1+q)^2(1+q^2)^2\cdots(1+q^n)^2}=:1+\sum_{n=1}^{\infty} \alpha(n)q^n,$ be the well-known third order mock theta of Ramanujan. Part of the...

Peter Donovan - University of New South Wales
There is a rather surprising relevance of the Artin-Hasse exponential to the Grothendieck Riemann-Roch theorem.

Paul Bryan - Macquarie University
The Harnack inequality plays a central role in the analysis of parabolic equations, such as through the strong maximum principle, regularity of weak solutions, Liouville type theorems for ancient...

Peng Gao - Beihang University
This seminar has been cancelled. The study on the mean values of the divisor function $d(n)$ has a long history. Using his hyperbola method, Dirichlet established a well-known asymptotic formula for...

Micah Milinovich - University of Mississippi
There are many situations where one imposes certain conditions on a function and its Fourier transform and then wants to optimize a certain quantity. I will describe how these types of Fourier...
