Pseudo-Anosovs are exponentially generic in mapping class groups

I Choi - arXiv preprint arXiv:2110.06678, 2021 - arxiv.org
Given a finite generating set $ S $, let us endow the mapping class group of a closed
hyperbolic surface with the word metric for $ S $. We discuss the following question: does …

Central limit theorem and geodesic tracking on hyperbolic spaces and Teichmüller spaces

I Choi - Advances in Mathematics, 2023 - Elsevier
We study random walks on the isometry group of a Gromov hyperbolic space or Teichmüller
space. We prove that the translation lengths of random isometries satisfy a central limit …

Entropy and drift for word metrics on relatively hyperbolic groups

M Dussaule, I Gekhtman - Groups, Geometry, and Dynamics, 2020 - ems.press
We are interested in the Guivarc'h inequality for admissible random walks on finitely
generated relatively hyperbolic groups, endowed with a word metric. We show that for …

Central limit theorems for counting measures in coarse negative curvature

I Gekhtman, SJ Taylor, G Tiozzo - Compositio Mathematica, 2022 - cambridge.org
We establish central limit theorems for an action of a group. Our techniques allow us to
remove the usual assumptions of properness and smoothness of the space, or …

Counting pseudo-Anosovs as weakly contracting isometries

I Choi - arXiv preprint arXiv:2408.00603, 2024 - arxiv.org
We show that pseudo-Anosov mapping classes are generic in every Cayley graph of the
mapping class group of a finite-type hyperbolic surface. Our method also yields an …

Excursions of generic geodesics in right-angled Artin groups and graph products

Y Qing, G Tiozzo - International Mathematics Research Notices, 2021 - academic.oup.com
Motivated by the notion of cusp excursion in geometrically finite hyperbolic manifolds, we
define a notion of excursion in any subgroup of a given group and study its asymptotic …

Statistical limit laws for hyperbolic groups

S Cantrell - Transactions of the American Mathematical Society, 2021 - ams.org
Using techniques from ergodic theory and symbolic dynamics, we derive statistical limit laws
for real valued functions on hyperbolic groups. In particular, our results apply to convex …

[HTML][HTML] Spherical and geodesic growth rates of right-angled Coxeter and Artin groups are Perron numbers

A Kolpakov, A Talambutsa - Discrete Mathematics, 2020 - Elsevier
We prove that for any infinite right-angled Coxeter or Artin group, its spherical and geodesic
growth rates (with respect to the standard generating set) either take values in the set of …
