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.

*Dr Julia Collins - University of Edinburgh*

There are many unexpected links between mathematics and knitting, and this talk will be an informal survey of some of the areas of overlap. We can use knitting and crochet to express mathematical...

*Georgy Sofronov - Macquarie University*

We observe a sequence of random variables and have to decide when we must stop, given that there is no recall allowed, that is, a random variable once rejected cannot be chosen later on. Our decision...

*Mark Watkins - University of Sydney*

The Riemann zeta-function is the most well-known example of a class of objects known as $L$-functions. Historically, it and the other degree 1 $L$-functions, those of Dirichlet, were the first to be...

*Eric Renault - Brown University*

We consider consistent estimation of parameters in a structural model by Indirect Inference (II) when the exogenous variables can be missing at random (MAR) endogenously. We demonstrate that II...

*Min Sha - UNSW*

In algebraic number theory, given a number field, the lattice derived from its embeddings by using its ring of integers is used to prove that the class number of the number field is finite. In this...

*János Pach - EPFL, Lausanne and Renyi Institute, Budapest*

By Ramsey's theorem, any system of n segments in the plane has roughly log n members that are either pairwise disjoint or pairwise intersecting. Analogously, any set of n points p(1),..., p(n) in the...

*Joe Ward - Texas A&M University, College Station*

Highly efficient representation and processing of multidimensional data (smoothing, compression, etc.) is best suited using approximation spaces with highly (spatially) localized bases. Over the past...

*Edgar Costa - Dartmouth College*

I will discuss a new simple and practical point-counting algorithm for curves over finite fields, given by plane models, possibly singular.This is joint work with David Harvey.

*Tianping Zhang - Shaanxi Normal University*

Let $p> 2$ be an odd prime. For each integer $b$ with $1\leq b<p$ and $(b, p)=1$, there is a unique integer $c$ with $1\leq c<p$ such that $bc\equiv 1(\bmod p)$. Let $M(1,p)$ denote the...
