Seminar Archive - 2010

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.

Associate Professor Gillian Heller - Macquarie University
We consider responses for which the measurement or observation error is substantial but to some extent predictable. Knowledge of the mechanism which perturbs the response leads to models in which the...

Allan Motyer - Prince of Wales Clinical School, UNSW
A quasi-birth-and-death process (QBD) is a two-dimensional Markov chain for which the transition matrix has a block tridiagonal structure, and is a widely studied stochastic model used in, for...

Professor John Geweke - University of Technology, Sydney
This study considers three alternative sources of information about volatility potentially useful in predicting daily asset returns : past daily returns, past intra-daily returns, and a volatility...

Professor Zdzislaw Brzezniak - The University of York (UK)
I will show that an approach from the paper Brzezniak and Ondrejat (2007) can be applied to the stochastic heat flow equation in the case when the domain is one dimensional. The one dimensionality of...

Dr Robb Muirhead - Pfizer Global R&D (USA)
Part 1: Consider a random rotation of a fixed point on a unit sphere in p-dimensions, where p is at least 3. For example, regard the earth as a unit sphere in 3 dimensions. You are standing near the...

Prof. Matthew Dyer - University of Notre Dame
We discuss a class of groupoids equipped with (abstract) root systems with very favourable properties. The motivating examples are Coxeter groups with their root systems, but they are also naturally...

Dr. Peter Donovan - UNSW
This discusses work of Leites, Berezin, Manin, Kac, and others who used some of Grothendieck's concepts to introduce supermanifolds. The good reference is the two-volume work of Deligne, Witten, and...

Dr. Anne Thomas - University of Sydney
Let I(p,v) be Bourdon's building, the unique simply-connected 2-complex such that all 2-cells are regular right-angled hyperbolic p-gons and the link at each vertex is the complete bipartite graph K_...

Dr Jiguo Cao - Simon Fraser University, Vancouver (Canada)
Differential equations describe the rate of change of a process. They are widely used in medicine, engineering, ecology and a host of other applications. One central and difficult problem is how to...

Dr. Rob Taggart - Australian National University
Given a smooth scalar field f supported in a ball and whose integral is zero, one can always find a smooth vector field v supported in the same ball such that div(v) = f. An operator which solves the...
