MaPS – MaPSS Seminar Series

Welcome to the webpage for the Mathematical Postgraduate Seminar Series (MaPSS). We’re committed to fostering a friendly atmosphere in the school of Mathematics and Statistics. All maths postgraduate students are encouraged to present. It’s an excellent opportunity to hone presentation skills and talk about fun new topics. Most of all, it’s a great way of getting to know your fellow students. So come along and meet some friends over free pizza!

If you or anyone you know is interested in presenting, or for any other enquiries, please contact the MaPSS organisers: Giulian Wiggins, Jonathan Mui, Sidney Holden and Wenqi Yue.

MaPSS also ran in 2015, 2016, 2017, 2018 and 2019.

See also the postgraduate reading groups.

Seminars in 2021, Semester 2

Due to covid restrictions, all seminars will be held at 5:00 pm on Mondays over Zoom

Sidney Holden (The University of Sydney) — The second derivative on high-density spider webs

Spiders are mostly blind. Yet they manage to `see’ the world by processing the vibration data they collect from their webs. In a sense, the spider’s web is an extension of the spider’s body. Would a dense enough spider’s web approximate continuous space, thereby allowing the spider to apply standard techniques from calculus? While it seems that spiders have lasted long enough without working this out, I will discuss a continuous Laplace-type operator that allows us to study diffusive-wave-quantum behaviour on high-density networks.

Jonathan Mui (The University of Sydney) — Random thoughts on PDEs

Recently I have developed a great interest in the stochastic interpretation of deterministic PDEs. In this informal talk, I will present some basic aspects of this theory, and hopefully illuminate some essential themes in modern PDE analysis with which I believe every mathematician should be acquainted. (Thus “random” in the title is interpreted both in the colloquial and mathematically rigorous senses.)

Our protagonists in this story will be the heat equation and Brownian motion. We will encounter a cast of colourful characters including stochastic integrals, It^{o} diffusions, and operator semigroups and their generators.

Monday, November 1st

George Papadopoulos (The University of Sydney) — What is “tertiary mathematics education research”, and why should we care?

In this talk I will provide a brief introduction to the research of mathematics education, focusing on the tertiary level as it is most applicable to members of our School. A selection of educational theories and frameworks will be introduced in general and then applied to the context of mathematics. Finally, we will discuss what motivates and emanates from academic research in tertiary mathematics education, and why it may be beneficial (or even essential) to be on our individual agendas and the School as a whole (with some interesting case studies presented).
