# Seminar Archive - 2009

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.

Professor David Balding - Imperial College London
Testing one SNP at a time does not fully realise the potential of genome-wide association studies to identify multiple causal variants, which is a plausible scenario for many complex diseases. We...

Prof. Gerd Rudolph - Leipzig
After a short introduction to the subject I will discuss the following points:The lattice gauge model as a Hamiltonian system with symmetriesSingular Marsden Weinstein reduction of this...

Dr Ursula Muller-Harknett - Texas A&M University
The problem of incomplete data is frequently encountered in many fields, with the health sciences and survey research being obvious examples, making the analysis of data sets with missing values an...

Dr. Peter Tingley - Melbourne
The crystals of the irreducible highest weight representations for affine $sl(n)$ have been studied extensively, and have various combinatorial models. We will discuss a few of these models, their...

Prof. Rajesh Kulkarni - Michigan State University
Maximal orders over discrete valuation rings were classically studied by many authors. In the more recent times, Michael Artin started the local study of maximal orders over two dimensional rings....

A/Prof. Ljiljana Brankovic - Newcastle
Data mining is now becoming a matchless tool for research and strategic planning and are used by companies, governments and research institutions alike. It depends on massive databases often...

Dr. Andrew Morris - ANU
Local Hardy Spaces of Differential Forms.

Dr. Anna Skripka - Texas A&M University
Spectral shift functions (SSF) provide information about a quantitative change of the spectrum of a self-adjoint operator under the influence of a self-adjoint perturbation. The first order SSF,...

Prof. Justin Sawon - Colorado State University
Coisotropic reduction can be regarded as a generalization of symplectic reduction. Given a symplectic manifold X of dimension 2n with symplectic form $\omega$, a submanifold Y of dimension at least n...

Professor Mohsen Pourahmadi - Texas A&M University
Finding an unconstrained and statistically interpretable reparameterization of a covariance matrix is still an open problem in statistics. Its solution is important in writing sparse and parsimonious...
