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.
Registered users will receive an email a few hours before the talk with a link to the Zoom meeting.
The seminar runs every Thursday. Please note the usual times of the seminar below and in the FAQ Section.

Abstract: Given an integral vector v in Euclidean n-space we project the standard lattice Z^n into the hyperplane orthogonal to v and obtain in this manner a "lattice of rank n-1" in that hyperplane, which is called "The directional lattice D(Z^n,v)".
In this talk I will discuss results about the limit distribution of directional lattices as we let the vector v vary in some natural sets from a number theoretic point of view. These include, balls, spheres, non-compact quadratic surfaces, and integral vectors approximating an irrational line.

Abstract: Arithmetic statistics, or the counting of objects of algebraic interest, has seen a lot of development in the last twenty years. We will take a glimpse into just a few recent advances, with an emphasis on the wide interplay of new tools and techniques.

Abstract: Recent work, joint with James Leng and Mehtaab Sawhney, improves the so-called “inverse theorem” for the Gowers $U^{s+1}[N]$-norm which arises in the field of additive combinatorics in relation to Roth’s and Szemerédi’s theorems. I will explain how the field of higher-order Fourier analysis broadly extends Fourier methods and the circle method in number theory, and discuss implications of bounds for inverse theorems.
