The 2013 Mahler Lecture by Akshay Venkatesh, Professor of Mathematics at Stanford University.
Surprisingly, there have been fundamental new discoveries about prime numbers in the last decade, most recently by Yitang Zhang a few months ago. In this lecture, Professor Venkatesh will survey (...)

Friday 27 
15:00  SEMINAR  Groups and Combinatorics Seminar, Straightline programs with memory and applications to computational group theory

More Information

Abstract:
Straightline programs offer a method for encoding group computations in a "black box" sense, namely without using specifics of the group's representation or how the group operations are performed. We advocate that straightline programs designed for group (...)

Friday 11 
15:00  SEMINAR  Groups and Combinatorics Seminar, Multiply tiling Euclidean space by translating a convex object

More Information

Abstract:
We study the problem of covering Euclidean space R^d by possibly overlapping translates of a convex body P, such that almost every point is covered exactly k times, for a fixed integer k. Such a covering of Euclidean space by translations is called a ktiling. We will first (...)

15:00  SEMINAR  Groups and Combinatorics Seminar, Regular orbits of Sym(n) and Alt(n) on irreducible representations

More Information

Abstract:
Given a finite group G and a faithful irreducible FGmodule V where F is a field of prime order, we can ask whether G has a regular orbit on the vectors of V. This problem is related to determining which primitive permutation groups of affine type have a base of size 2, as well (...)

18:00  LECTURE  27th Dr George Hondros Memorial Lecture : Unique designs — the power of multidisciplinary collaboration. Delivered by Tristram Carfrae AwardWinning Structural Engineer, Director and Arup Fellow.

More Information

Tristram Carfrae is responsible for the design of an impressive array of awardwinning buildings and is regarded internationally as a leading designer of light weight longspan structures.

Friday 25 
15:00  SEMINAR  Groups and Combinatorics Seminar, Coprime actions of finite linear groups

More Information

Abstract:
Let H be a finite linear group acting completely reducibly on a finite vector space V. Gabriel Navarro asked: if the Horbits containing vectors a and b have coprime lengths m and n, is there an Horbit of length mn?
We answered, by showing that the Horbit containing a + b (...)

Friday 01 
15:00  SEMINAR  Groups and Combinatorics Seminar, Algebraic geometry codes

More Information

Abstract:
Codes arising from algebraic geometry, first introduced by Goppa, gained attention when Tsfasman–Vladut–Zink used them to improve the GilbertVarshamow bound. We will give a gentle introduction to some of the beautiful ideas from algebraic geometry used to build these codes (...)

Tuesday 12 
R is a free and extremely powerful language and software environment for statistical computing, data analysis, and graphics. The course is designed for those who have no experience with R, but have a basic understanding of statistics. The course will include:
Introduction to R: How to install R on (...)

Wednesday 13 
Professor Tilling main areas of expertise are in methods for
analysing exposures and outcomes across the lifecourse, and in methods for dealing with missing data. She has a mathematical background, an MSc in Applied Statistics and a PhD in Epidemiology, together with more than 15 years’ experience (...)

Thursday 14 
The course will cover material ranging from a review of simple oneway ANOVA, to more complex designs and analyses including crossed and nested factors with fixed and random effects.The emphasis throughout will be placed on applications rather than theory. The statistical package R and R Commander (...)

12:00  SEMINAR  Confronting the killer: epidemiology and prevention of pneumonia in Papua New Guinean children

Website 
More Information

The Lung Institute of WA invites you to a free seminar on: "Confronting the killer: epidemiology and prevention of pneumonia in Papua New Guinean children" by Associate Professor Deborah Lehmann. A light lunch will be served from 12.00pm with a 12.30pm – 1.30pm presentation.
In 1950’s Fermi, motivated by fundamental questions of statistical mechanics, started a numerical experiment in collaboration with Pasta and Ulam to test the ergodic properties of nonlinear dynamical systems. The chosen socalled FPU system was a one dimensional chain of N nonlinear coupled (...)

Friday 22 
Selfavoiding walks (SAWs) are widely studied as a problem in algebraic combinatorics by mathematicians, as a problem in algorithm design by computer scientists, as a model of phase transitions by mathematical physicists and as a model of polymers in dilute solution by chemists.
