*Nick Fewster - UNSW*

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...

*Robyn Stuart - UNSW*

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...

*Georgy Sofronov - Macquarie University*

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...

*Randell Heyman - UNSW*

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

*Dr. Terence Chan - University of South Australia*

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...

*Dr. Daniel Chan - UNSW*

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...

*Prof. Tomasz Downarowicz - Wrocław University of Technology, Poland*

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...

*Dr. Daniel Chan - UNSW*

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...

*Darryl Lewis and Patrick McComish - UNSW and TeamBoard*

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...

*Assoc. Prof. Frank Calegari - Northwestern University*

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...
