UNSW Number Theory Seminar
This is the unofficial home page of the UNSW Number Theory Seminar.
We welcome talks on current research topics and also talks of a more expository nature.
Speakers are encouraged to make at least part of their talk accessible to advanced undergraduates (i.e. Honours students).
The seminar is organised by
Alina Ostafe
and
David Harvey.
Please contact the organisers if you wish to be added to (or subtracted from) the mailing list.
