Krishnendu Gongopadhyay - Indian Institute of Science Education and Research (IISER) Mohali
Let $SU(n,1)$ be the isometry group of the $n$-dimensional complex hyperbolic space. An element $g$ in $SU(n,1)$ is called loxodromic or hyperbolic if it has exactly two fixed points on the boundary...

Zac Murphy - University of New South Wales
At first glance, quotient categories might seem like a strange notion to define, but in actuality they turn out to be quite useful constructions. On one hand, they simplify the treatment of certain...

Stephen Maher - Lancaster University
Packing rings into a minimum number of rectangles is an optimization problem that appears naturally in the logistics operations of the tube industry. Considering each rectangle as a transportation...

Matthew Hircock - University of New South Wales
The numerical range was first studied in 1918 as a useful tool for localising the spectrum of a linear operator on a Hilbert space. The convexity of this localisation limits how much information we...

Margaret Clemson - UNSW and Kincoppal-Rose Bay School
The 2017 Teaching Fellow in the School of Mathematics and Statistics at UNSW is Margaret Clemson who comes to us from Kincoppal-Rose Bay School. In this seminar she will reflect on her experiences...

Yu Guang Wang - La Trobe University, Melbourne and UNSW,Sydney, Australia
This work gives the exact solution in terms of the Karhunen-Loève expansion to a fractional stochastic partial differential equation on the 2-dimensional unit sphere with fractional Brownian motion...

Andrew Schopieray - University of New South Wales
The classical McKay correspondence characterises finite subgroups of SU(2) by associating them with a very restrictive family of graphs.   This can be rephrased in modern language as a classification...

Mumtaz Hussain - La Trobe University
Let $\psi:\mathbb R_+\to\mathbb R_+$ be a non-increasing function. A real number $x$ is said to be $\psi$-Dirichlet improvable if it admits an improvement to Dirichlet's theorem in the following...

Antoine Joux - Laboratoire d'informatique de Paris 6
We consider the problem of solving multivariate systems of Boolean polynomial equations: starting from a system of $m$ polynomials of degree at most $d$ in $n$ variables, we want to find its...

Paul Spence - UNSW Climate Change Research Centre
In honours of Walter Munk's 100th birthday, Paul Spence will present a general interest talk on the science of surfing. Does God want us to surf? Is there any difference between a surfer and a drug...
