# 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...
