"$p$-Adic interpolation of orbits under rational maps"

Rivera-Letelier’s characterization of possible analytic uniformizations of $p$-adic analytic maps has played an important role within arithmetic dynamics over the past fifteen years. The characterization is given by a trichotomy of indifferent, attracting and superattracting cases near a fixed point of a map.

"Hyperkähler structure of bow varieties"

My aim is to discuss some of the background material necessary to understand the recent paper of Roger Bielawski, Yannic Borchard, and Sergey Cherkis titled “Deformations of instanton metrics” (https://arxiv.org/abs/2208.14936).

"An improvement to the Schmidt bound"

Counting number fields of fixed degree and bounded discriminant is a classical question in arithmetic statistics. The problem is known in degrees at most 5. In this talk, we will talk about an improvement to Schmidt's upper bound for general degree n, which beats existing improvements for n up to 94. This is joint work with Manjul Bhargava and Arul Shankar.

This seminar will be held jointly online and in person:
