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.

Professor Noel Cressie - University of Wollongong
In this talk, I give a hierarchical-statistical-modelling framework for uncertainty quantification for inferring marine biogeochemical cycles. Uncertainties appear in the (noisy and incomplete) data...

Peter Dragnev - Indiana University-Purdue University Fort Wayne
In this presentation we prove that the equilibrium measure of a finite union of intervals on the real line or arcs on the unit circle has convex density. This is true for both, the classical...

Masoud Kamgarpour - University of Queensland
Studying symmetries is one of the most powerful tools available to scientists for making sense of the world.  In this talk, I will start by explaining how symmetries of geometric objects give rise to...

Sanjaya Dissanayake - University of Sydney
This talk presents an approximation of a Gegenbauer autoregressive moving average (GARMA) process driven by Gaussian white noise. The process model characterised by long memory using a finite order...

David Penneys - University of Toronto
We classify subfactors by three invariants of increasing complexity: the index, the principal graph, and the standard invariant. The standard invariant is a unitary 2-category which generalizes the...

Anna Novikova - Weizmann Institute of Sciences
TBA

Professor Kanta Naito - Shimane University, Japan
In multi-class discriminant analysis for High Dimension Low Sample Size settings it is not possible to define Fisher’s discriminant function, since the sample covariance matrix is singular. For the...

Konrad Schöbel - University of Jena, Germany
We establish a surprising link between two a priori completely unrelated objects:  The space of isometry classes of separation coordinates on an n-dimensional sphere one one hand and the Deligne-...

Andrew Morris - University of Oxford
We consider the layer potentials associated with operators $L=-\mathrm{div}A \nabla$ acting in the upper half-space $\mathbb{R}^{n+1}_+$, $n\geq 2$, where the coefficient matrix $A$ is complex,...

David Evans - Cardiff University
Subfactor theory provides a framework for studying modular invariant partition functions in conformal field theory, and candidates for exotic modular tensor categories. I will describe work with...
