Quasi-trees and product set growth
- 👤 Speaker: Alice Kerr (University of Oxford)
- 📅 Date & Time: Friday 04 June 2021, 13:45 - 14:45

Abstract
A standard question in group theory is to ask if we can categorise the subgroups of a group in terms of their growth. In this talk we will be asking this question for uniform product set growth, a property that is stronger than the more widely understood notion of uniform exponential growth. We will see how quasi-trees could help us answer this question for acylindrically hyperbolic groups, and give a particular application to right-angled Artin groups.
Series This talk is part of the Geometric Group Theory (GGT) Seminar series.
