# Seminar Archive - 2018

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.

Gary Liang - University of New South Wales
Greenhill, Kwan and Wind determined the asymptotic distribution of the number of spanning trees in a random cubic graph using the small subgraph conditioning method. They conjectured that a similar...

Xiao Xiong - Institute for Advanced Study in Mathematics, Institute of Technology, Harbin
We will introduce our recent work on pseudo-differential operators in noncommutative setting. We focus on two main topics: symbolic calculus and regularities on function spaces. We describe the...

Dr. John Ormerod - University of Sydney
We introduce a new class of priors for Bayesian hypothesis testing, which we name "cake priors". These priors circumvent Bartlett's paradox (also called the Jeffreys-Lindley paradox); the problem...

Erik Van Sebile - Institute for Marine and Atmospheric Research, Utrecht University, Netherlands
Ocean currents and eddies carry floating plastic litter from coastlines into the infamous garbage patches in the centres of the gyres. However, the time scales and pathways on which this happens are...

Enrico Le Donne - Research Fellow of the Finnish Academy, Associate professor (Yliopistonlehtori) at University of Jyväskylä, Finland
The objective of this talk is to give a new point of view for the validity of Fefferman's mapping theorem from 1974. This result states that a biholomorphism between two smoothly bounded strictly ...

Milena Radnovic - University of Sydney
A comprehensive study of periodic trajectories of the billiards within ellipsoids in d-dimensional space is presented. The novelty of the approach is based on a relationship established between the...

Prof. Anthony J. Richardson - Queensland University, CSIRO
Plankton are the microscopic plants and animals at the base of the marine foodweb that produce half the oxygen we breathe and support most of the fish we consume. Despite nearly a century of research...

Laure Helme-Guizon (Dr H) - School of Mathematics and Statistics, UNSW Sydney
In this reflection about my year as a Teaching Fellow at UNSW, I will explain what I did, what I learned, and what the challenges have been. It has been suggested to me to also include a few words...

Ben Madafiglio - University of New South Wales
In 1970, Cheeger bounded the lowest nonzero eigenvalue  $\lambda_1$ of the Laplacian on a Riemannain manifold using a geometrical property now known as the Cheeger isoperiemtric constant. Cheeger's...

Felipe Voloch - University of Canterbury
An error correcting code is a subspace of $k^n$, where $k$ is a finite field. Such a code is said to be locally recoverable with locality $r$ if, for every coordinate of a codeword, its value can be...
