Number Theory Down Under

This is the official website of the Number Theory Down Under (NTDU) interest group of the Australian Mathematical Society (AustMS).

The NTDU interest group was officially recognised in 2015 as part of AustMS, but has been active since 2013 when the series of Number Theory Down Under Conferences was initiated in Newcastle as a one day workshop. This annual event has since become one of the regular activities of the group, and has transformed into a full scale international conference, promoting number theory in Australia. It brings together Australian and international number theorists to share ideas, pursue collaborative work and establish connections to other fields of mathematics.


The conference "Number theory Down Under 9" will take place on September 27 - 30, 2021. It will be run in hybrid mode: in person, at the University of Sydney, and online.

More information about the conference can be found on its webpage.
