*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...
