## Talk on Friday 10 October

On Friday, 10 October, Stephen Tate (Warwick) will talk in the Combinatorics Study Group on “Combinatorics in Statistical Mechanics”, a talk which will be of wider interest.

Further details can be found here.

## New Director

The new director of the Centre for Discrete Mathematics is Professor David Arrowsmith.

We thank Peter Keevash for all he has done for the Centre, and wish David well in the job.

## Talk by Peter Harremoes

**Speaker:** Peter Harremoës

**Time and Place: **

4pm, 16 January 2013, in Maths Room 203 at 4pm and is followed by a reception at 5pm in the Maths Foyer.

**Title:** Occam’s Razor in Action – information as link between statistics and probability theory

**Abstract:** Probability theory and statistics are normally considered as two distinct but related fields of mathematics. In this talk I will demonstrate how ideas from information theory may be used to glue all three fields together.

In the first part of the talk I will discuss some basic but important information theoretic concepts and results like codes, Kraft’s inequality, entropy, information divergence, and rate distortion theory. In the second half of the talk I will give a short overview of the newest results on how all the basic theorems of probability theory can be reformulated so that the results become stronger and so that the proofs become simpler and so that applications become more directly applicable in statistics.

The talk will include the presentation of a number of open problems.

## Combinatorial Probability and Statistical Mechanics Workshop

We are pleased to announce the Workshop

*Combinatorial Probability and Statistical Mechanics*

to be held on 21 – 23 February 2013 in Queen Mary, University of London.

The workshop is the first in the new series of meetings co-organised by the School of Mathematical Sciences at QMUL and the Mathematics Institute of the University of Warwick.

The aim of the workshop is to bring together researchers who study various aspects and applications of random combinatorial structures, in particular from the viewpoints of stochastic processes, asymptotic enumeration, analytic combinatorics and the analysis of algorithms.

The website for the workshop is here.

If you are coming to the workshop, it would be helpful if you email D.S.Stark@qmul.ac.uk, so that we have some idea of the number of attendees.

Please note that the Queen Mary Algorithms Day will be the day before the workshop; you may wish to attend both.

## Talk by Van Vu

**Note 22/10/2012**: This talk has been cancelled because of ill-health.

Van Vu (Yale) will speak in the Pure Mathematics Colloquium at Queen Mary on **Monday, 22 October 2012**, at **4:00pm** in room M103 (Mathematical Sciences building). Please note the change of time! The title is *Random matrices: Law of the determinant*.

Abstract:

We will discuss the obvious question raised in the title. The problem has been considered for quite a while, with partial results from Turan, Komlos, Dixon, Girko, Delannay-Le Caer, Dembo and many others.

We will give a brief survey and then focus on recent results of Tao, Nguyen, and the speaker which give answers for quite general setting. If time allows, we will also discuss a few open questions.

## A date for your diary

The Queen Mary Algorithms Day will take place on 20 February 2013. A list of speakers can be found on the webpage.
