*Scott Maxwell - Information Gateways Pty Ltd*

Scott Maxwell from Ed Stem will give a demonstration of updated features of the integrated discussion platform developed for use in STEM courses. Here in the UNSW School of Mathematics and...

*Adrian Miranda - University of New South Wales*

Category theory allows a precise formulation of relationships between structures that emerge from seemingly different contexts across mathematics. One would like to study not just the properties of...

*Peng Gao - Beihang University, Beijing, China*

The density conjecture of Katz and Sarnak suggests that the distribution of zeros near 1/2 of a family of $L$-functions is the same as that of eigenvalues near 1 of a corresponding classical compact...

*Joseph Gunther - City University of New York*

How many algebraic numbers are there? Easy: infinitely many. But if we bound their degree and height, we get an interesting counting problem. Answering it involves counting lattice points in...

*Darryn Waugh - Johns Hopkins University and UNSW Mathematics and Statistics*

The term “polar vortex” has become part of the everyday vocabulary (at least in the USA), but there is some confusion in the media, general public, and science community regarding what polar vortices...

*Peter McComb - MetOcean Solutions, New Zealand*

The Southern Ocean represents around 22% of the global sea surface area. The combination of persistent westerly winds, and the largely unbroken expanse of sea, produces potentially enormous fetches,...

*Michael Ehrig - Univesity of Sydney*

The family of Brauer algebras was originally defined in 1937 by Brauer to solve a problem in classic invariant theory.
The talk will give an overview on how this family relates to other areas of...

*Joseph Gunther - University of Wisconsin-Madison*

On a hyperelliptic curve over $\mathbb{Q}$, there are infinitely many points defined over quadratic fields: just pull back rational points of the projective line through the degree two map. But for...

*Bryce Kerr - UNSW*

This talk concerns some recent results of the author about incomplete Gauss sums modulo primes. We outline the methods used for obtaining new quantitative bounds and discuss how these results fit in...

*Hard Hulley - UTS*

Short sales are represented as negative purchases in textbook asset pricing theory. In reality, however, the symmetry between purchases and short sales is broken by a variety of costs and risks...
