About the Conference

This will be a conference bringing together researchers in all areas of Number Theory. It will be held online, so instead of being localised geographically, it will be localised in a range of time-zones, specifically time-zones near Australia. Thus most participants are from Australia, New Zealand, Japan, South Korea and Taiwan.

Holding conferences online rather than in person has many benefits. The necessity in the time of COVID-19 is obvious: in-person conferences are currently impossible and will most likely remain impossible or at best inadvisable for the rest of 2020. Furthermore, even after this emergency has passed, we should be holding more events online, as this greatly reduces the financial and environmental impact of academic conference travel.

Conferences play a very important social role in academia, and this can be hard replicate online. For this reason we will host the conference using the iSee platform, which is a 3D virtual environment where participants can mingle in a natural way between talks, facilitating networking and initiating new collaborations in a way that other video-conferencing platforms can't match.

Important Dates

Titles and abstracts due: 22 May 2020
Registration closes: 29 May 2020
Conference: 3-5 June 2020 (Wed-Fri)

Abstract Submission

Abstracts can be submitted through our abstract submission system, and close on 22 May. You need to register for the system: a confirmation link will be emailled to you. You can use basic Latex code in your abstract (but not, for example, environments or figures).


You can register now through the conference Eventbrite page. Please note that this is a separate process to submitting your abstract.

AMSI requires us to charge a registration fee. If you have unspent (and currently unspendable) travel funds, you can use them to pay the registration fee below. Otherwise, feel free to ask for a fee waiver (do so by "buying" one free "Apply for fee waiver" ticket, and not the "Full Registration" or "AMSI/AustMS/ANZIAM member" tickets) . The registration fees are as follows:

Full registration fee:AUD$75
Reduced fee (AMSI, AustMS or ANZIAM members):AUD$50


The workshop will be held completely on-line. Details of the software are sent to registrants.
