# Seminar Archive - 2011

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.

The change-point problem arises in wide variety of fields, including biomedical signal processing, speech and image processing, seismology, industry (e.g., fault detection) and financial mathematics. Multiple change-point models are also important...

I will present map, drawn onto a a plane and separated into contiguous regions, which requires an arbitrarily large number of colours in order to ensure that no two adjacent regions have the same colour.  Such a map is contrary to the intuitive...

This talk will explore some interesting fractal patterns in geometric measure theory with a short introduction to Hausdorff measure. A Besicovitch set is any set of points in Euclidean space which contains a unit line segment in every direction. In...

These talks are designed to be interesting, fun, not difficult and a change from the subject matter of first year mathematics courses.

Information inequalities are well-known as the basic laws governing the fundamental limits in data transmission and compression. These inequalities are also closely related to different areas including matroid theory, group theory, linear algebra,...

The theory of orders has been variously described as a form of non-commutative arithmetic or non-commutative algebraic geometry. Examples of orders include group rings over rings of integers in the arithmetic case, and Azumaya algebras in the...

A "doubly stochastic operator" is a continuous linear operator $T: L^1(\mu) \to L^1(\mu)$ ($\mu$ is a probability measure) which is nonnegative, preserves constants and preserves the integral. Such operators generalize standard dynamical systems as...

The theory of orders has been variously described as a form of non-commutative arithmetic or non-commutative algebraic geometry. Examples of orders include group rings over rings of integers in the arithmetic case, and Azumaya algebras in the...

Technology in teaching is moving at a rapid clip, and sometimes it can be a struggle to keep up. This talk will discuss two important developments for us here in the School of Mathematics and Statistics: Lectopia and our new Access Grid Room RC 4082...

How much does the cohomology of an algebraic variety tell us about the variety itself? The answer, at least according to a conjecture of Tate, is quite a lot. In this talk, I will try to outline the relationship -- mostly conjectural -- between...
