Random walks and contracting elements I: Deviation inequality and limit laws

I Choi - arXiv preprint arXiv:2207.06597, 2022 - arxiv.org
We study random walks on metric spaces with contracting isometries. In this first article of the
series, we establish sharp deviation inequalities by adapting Gou\" ezel's pivotal time …

Confined subgroups in groups with contracting elements

I Choi, I Gekhtman, W Yang, T Zheng - arXiv preprint arXiv:2405.09070, 2024 - arxiv.org
In this paper, we study the growth of confined subgroups through boundary actions of
groups with contracting elements. We establish that the growth rate of a confined subgroup …

Conformal dynamics at infinity for groups with contracting elements

W Yang - arXiv preprint arXiv:2208.04861, 2022 - arxiv.org
This paper develops a theory of conformal density at infinity for groups with contracting
elements. We start by introducing a class of convergence boundary encompassing many …

Curtain Characterization of Sublinearly Morse Geodesics in CAT (0) Spaces

E Vest - arXiv preprint arXiv:2309.02725, 2023 - arxiv.org
We show that the sublinear Morse boundary of every CAT (0) space continuously injects into
the Gromov boundary of a hyperbolic space, which was not previously known even for all …

The Curtain Model of CAT (0) Spaces and its Relationship to the Sublinearly Morse Boundary

ES Vest - 2024 - search.proquest.com
We show that the sublinear Morse boundary of every CAT (0) space continuously injects into
the Gromov boundary of a hyperbolic space, which was not previously known even for all …

Sublinearly Morse boundary, II: Proper geodesic spaces

Y Qing, K Rafi, G Tiozzo - Geometry & Topology, 2024 - msp.org
We build an analogue of the Gromov boundary for any proper geodesic metric space, hence
for any finitely generated group. More precisely, for any proper geodesic metric space X and …

Geometry and dynamics on sublinearly Morse boundaries of cat (0) groups

Y Qing, A Zalloum - Pacific Journal of Mathematics, 2024 - msp.org
Given a sublinear function κ, κ-Morse boundaries∂ κ X of proper CAT⁡(0) spaces are
introduced by Qing, Rafi and Tiozzo (2024). It is a topological space that consists of a …

[PDF][PDF] QUASI-REDIRECTING BOUNDARIES OF NON-POSITIVELY CURVED GROUPS

A MARGOLIS, HT NGUYEN, Y QING - math.utk.edu
In this paper, we show that the quasi-redirecting boundary (QR boundary) is well-defined as
a topological space for several classes of groups with nonpositive curvature: admissible …
