Seminar Archive - 2013

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.

William McLean - UNSW
The discontinuous Galerkin method provides a flexible and unconditionally stable time discretization for fractional diffusion and wave equations.  I will outline the results of joint work with Kassem...

Michael Cowling - UNSW
Von Neumann asked whether every non-amenable group contains a free subgroup.  The answer is no.  I will give an account of a simple proof of this due to Nicholas Monod.

Prof John Robinson - The University of Sydney
In general nonparametric tests have been based on test statistics chosen to have good properties in related parametric problems. Bootstrap or asymptotic approximations for the distribution of the...

Thomas Westerbäck - KTH Royal Institute of Technology
The theory of linear codes over finite fields has long been strengthened by combinatorial theory, and matroid theory has shown to be particularly well suited for providing a theoretical foundation...

Elisabeth Kava - UNSW
The canonical commutation relations (CCR's) are at the foundation of quantum mechanics and quantum field theory. To properly analyse the CCR's, which involve unbounded operators, we encode them in a...

Eyvindur Ari Palsson - University of Rochester
As big data sets have become more common the interest in finding and understanding patterns in them has grown. A classical question on patterns (i.e. configurations), known as the Erdos distinct...

Dr Sara Taskinen - University of Jyvaskyla (Finland)
Classical multivariate methods (principal component analysis, multivariate regression, canonical correlation analysis, etc.) are based on the concepts of location vector and scatter matrix, and the...

Denis Potapov - UNSW
One of the open questions in the theory of Schatten ideals S^p of compact operators is whether their norms have the same differentiability properties as the norms of their commutative counterparts. ...

Martin Dyer - University of Leeds
In the counting constraint satisfaction problem (#CSP), we wish to know how  many ways there are to satisfy a given system of constraints on a set of variables, where a constraint is  a relation...

Dr Zdravko Botev - School of Mathematics and Statistics, UNSW
In this talk we present a new approach to rare-event probability estimation, in which the quantity of interest is the solution to a convex optimization problem. We show that this indirect method of...
