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.

Sean Lynch - University of New South Wales
The large sieve inequality is ubiquitous in analytic number theory and is a crucial ingredient in big results such as the Bombieri-Vinogradov Theorem and the Grand Density Theorem. Roughly speaking,...

Prof N J Wildberger - School of Mathematics and Statistics, UNSW Sydney
Coxeter-Dynkin graphs feature prominently in dozens of topics in modern mathematics, including Lie algebras and Lie groups, reflection groups, regular polytopes, lattice theory, singularities, root...

Prof N J Wildberger - School of Mathematics and Statistics UNSW
A general connected simple graph supports a rich geometry. This is determined by a quadratic form arising from the Mutation Game, and generalizing the Cartan matrix for ADE graphs. An associated root...

Simon Mak - Georgia Institute of Technology, USA
  Low-rank matrices play a vital role in many important problems in statistics, machine learning, and applied mathematics. For many such problems, the desired low-rank matrix cannot be directly...

Tsuyoshi Kato - Kyoto University
We define a twisted Donaldson’s invariant using the Dirac operator twisted by flat connections when the fundamental group of a four manifold is free abelian.  We also present its applications and...

Prof N J Wildberger - School of Mathematics and Statistics, UNSW Sydney
A general connected simple graph X supports a rich metrical geometry, fascinating combinatorics and tight connections with reflection/Coxeter group theory. This can all be laid out in an elementary...

Bishnu Lamichhane - University of Newcastle
In this talk we will briefly introduce the mixed finite element method and show its applications. We start with a simple mixed formulation for the Poisson problem and then consider different mixed...

Dr Peter Donovan - School of Mathematics and Statistics, UNSW Sydney
This talk deals with an elementary introduction to quivers, particularly those based on the extended Dynkin diagrams ~A_n, ~D_n, ~E_6, ~E_7 and ~E_8. It covers constructions rather than proofs. The...

Prof. Irène Gijbels - KU Leuven, Belgium
In this talk we study a general class of asymmetric distributions. Their probabilistic properties lead to explicit expressions for all main characteristics (mean, variance, skewness, kurtosis, ...)....

Arnaud Brothier - University of New South Wales
The Thompson group is the group of homeomorphisms of [0,1] that are piecewise linear with slopes a power of 2 and breakpoints a dyadic rational. It is one of the most studied discrete group which...
