# Seminar Archive - 2014

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.

Prof Louise Ryan - University of Technology, Sydney
This seminar will discuss the challenge of covariate selection in environmental epidemiology. We will highlight some of the pitfalls that can lead to erroneous inference when naive approaches are...

Peter McNamara - University of Sydney
Quantum groups are objects that first arose in mathematical physics, and in subsequent times have found applications in fields as diverse as constructing knot invariants and studying algebraic groups...

Johann Brauchart - UNSW
I will present an anecdotal foray into my research contributions of the past four years. Focal points will be numerical integration and the minimal energy problem on the sphere. I will give several...

Kial Stewart - UNSW / Climate Change Research Institute
Eddies are ubiquitous in the oceans. Certain circumstances permit interaction between the eddy and mean flow fields, requiring ocean models to either completely resolve the eddies or parameterize...

Kang Zuo - University of Mainz, Germany
The notion Higgs-de Rham flow'' over schemes  X/W(k) over the ring of Witt vectors of finite field k of characteristic p  introduced in a recent paper by Lan-Sheng-Zuo has found some interesting...

Prof Jiti Gao - Monash University
This paper proposes a general nonparametric regression approach to the estimation and computation of posterior means. We first consider the case where the samples can be independently drawn from both...

Ivan Graham - University of Bath
This is joint work with Paul Childs (Schlumberger Gould Research, Cambridge),  Martin Gander (Geneva), Euan Spence (Bath),  Douglas Shanks (Bath) and Eero Vainikko (Tartu). As a model problem for...

Adam Sorensen - University of Wollongong
In this talk we will look at square matrices A and B that satisfy that AB is close to BA. That is to say, matrices A and B that almost commute. I will explain what it means (to operator algebraists)...

Prof. Jean-Luc Thiffeault - University of Wisconsin - Madison
As fish, microorganisms, or other bodies move through a fluid, they stir their surroundings.  This can be beneficial to some fish, since the plankton they eat depends on a well-stirred medium to feed...

Prof Paul SF Yip - University of Hong Kong, Dep. of Social Work and Social Administration, Centre for Suicide Research and Prevention
A Markov chain illness and death model is proposed to determine suicide dynamic in a population and examine its effectiveness for reducing the number of suicides by modifying certain parameters of...
