# Seminar Archive - 2016

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.

Chris Oates - University of Technology, Sydney
This talk is about an exciting new area of research called Probabilistic Numerics. I will argue that statisticians have a central role to play in contemporary numerical analysis and provide an...

Mark Veraar - TU Delft
In this talk I will give an overview of some recent developments in the theory of vector-valued Sobolev spaces connected to PDE. - Characterizations of temporal traces of intersection of function...

Michael Baake - Bielefeld
Model sets, which go back to Yves Meyer (1972), are a versatile class of structures with amazing harmonic properties. They are particularly relevant for mathematical quasicrystals. More recently,...

Alexander Bors - Salzburg
In the literature, there are various results stating that a finite group in which a certain parameter (e.g., the number of conjugacy classes or the number of prime order subgroups) is large enough...

Alex Townsend - MIT
A classical technique for computing with functions on the sphere and disk is to "double wrap" the domain. We synthesize this with new techniques for constructing low rank function approximations to...

Melvin Faierman - UNSW
We consider a spectral problem over $\mathbb{R}^n$ for a Douglis-Nirenberg system of diﬀerential operators under limited smoothness asumptions as well as under the assumption of parameter-ellipticity...

Jörg Jahnel - Siegen
In this talk, I report about del Pezzo surfaces of degree 4 and cubic surfaces that violate the Hasse principle. The historically first such examples were constructed by Swinnerton-Dyer. Recently, we...

Gerry Myerson - Macquarie
I'll discuss some problems that have bothered me for a while on small sums of roots of unity, on covering congruences, and on semi-magic squares. Among the questions I may discuss are: How small can...

Ryo Furue - Japanese Agency for Marine-Earth Science and Technology (JAMSTEC)
At 5,500 kilometres, the Leeuwin Current is the world's longest coastal or boundary current and arguably Australia's most influentual natural feature. Originating at North West Cape, it flows...

Alex Townsend - MIT
A fundamental idea in matrix linear algebra is the factorization of a matrix into simpler matrices, such as orthogonal, tridiagonal, and triangular.  In this talk we extend this idea to a...
