Welcome to the First Online Seminar dedicated to Group Theory and Non-Commutative Algebra.

The seminar presents a unique opportunity for mathematicians from around the world to communicate and share their ideas on a regular basis without leaving the office or even home. Participants include faculty and students from US, Canada, Australia, Europe and Russia.

If you are a first-time participant please visit the technical advice page.

"Conjugacy growth and hyperbolicity"

Click here to enter the meeting room


The topic of the talk is conjugacy growth in groups, as well as conjugacy growth series and conjugacy related languages. In particular, I will discuss the positive answer to a conjecture of I.Rivin, which states that the conjugacy growth series of a hyperbolic group is rational if and only if the group is virtually cyclic.
I will present the proof that the conjugacy growth series of a non-elementary hyperbolic group is transcendental, result that can then be used to show a formal language version of Rivin's conjecture for any finitely generated acylindrically hyperbolic group (joint with Antolín).
If time allows, I will also show why the conjugacy growth series of a virtually cyclic group is rational (joint with Hermiller, Holt and Rees).
