Number Theory Web Seminar
This number theory seminar is purely online. Our talks come from various corners of the field and of the world. They are streamed live on Zoom.
Organizers:
Michael Bennett (University of British Columbia)
Philipp Habegger (University of Basel)
Alina Ostafe (UNSW Sydney)
There are no fees, but registration is necessary. To register please follow this link.

Abstract: The closest thing to a general method for counting primes in a set is the method of Type I/II sums. This allows one to obtain an asymptotic formula (or perhaps a non-trivial lower bound) for the number of primes in the set, provided one has sufficiently good estimates for certain auxiliary sums.
Unfortunately what counts as 'sufficiently good' is poorly understood, as are the limits of this approach. In this talk, I'll discuss a new framework (joint with Kevin Ford) which allows us to prove necessary and sufficient conditions in various cases, focusing on general features and illustrating the method with some simple examples.

In this talk I'll talk a new framework (joint with James Maynard) which allows us to prove various necessary and sufficient conditions, focusing on methods for constructing sets that satisfy the Type I and Type II bounds yet contain no primes. In particular, I will go into some detail about how to prove that a substantial 'Type II range' is necessary to deduce the existence of primes in a set.
