Martin boundary covers Floyd boundary

I Gekhtman, V Gerasimov, L Potyagailo… - Inventiones …, 2021 - Springer
For a random walk on a finitely generated group G we obtain a generalization of a classical
inequality of Ancona. We deduce as a corollary that the identity map on G extends to a …

The fundamental inequality for cocompact Fuchsian groups

P Kosenko, G Tiozzo - Forum of Mathematics, Sigma, 2022 - cambridge.org
We prove that the hitting measure is singular with respect to the Lebesgue measure for
random walks driven by finitely supported measures on cocompact, hyperelliptic Fuchsian …

Entropy and drift for Gibbs measures on geometrically finite manifolds

I Gekhtman, G Tiozzo - Transactions of the American Mathematical Society, 2020 - ams.org
We prove a generalization of the fundamental inequality of Guivarc'h relating entropy, drift
and critical exponent to Gibbs measures on geometrically finite quotients of $ CAT (-1) …

Counting conjugacy classes in groups with contracting elements

I Gekhtman, W Yang - Journal of Topology, 2022 - Wiley Online Library
In this paper, we derive an asymptotic formula for the number of conjugacy classes of
elements in a class of statistically convex‐cocompact actions with contracting elements …

Stability phenomena for Martin boundaries of relatively hyperbolic groups

M Dussaule, I Gekhtman - Probability Theory and Related Fields, 2021 - Springer
Let Γ Γ be a relatively hyperbolic group and let μ μ be an admissible symmetric finitely
supported probability measure on Γ Γ. We extend Floyd–Ancona type inequalities from …

Local limit theorems in relatively hyperbolic groups II: the non-spectrally degenerate case

M Dussaule - Compositio Mathematica, 2022 - cambridge.org
This is the second of a series of two papers dealing with local limit theorems in relatively
hyperbolic groups. In this second paper, we restrict our attention to non-spectrally …

Branching Random Walks on relatively hyperbolic groups

M Dussaule, L Wang, W Yang - arXiv preprint arXiv:2211.07213, 2022 - arxiv.org
Let $\Gamma $ be a non-elementary relatively hyperbolic group with a finite generating set.
Consider a finitely supported admissible and symmetric probability measure $\mu $ on …

Ratio-limit boundaries for random walks on relatively hyperbolic groups

A Dor-On, M Dussaule, I Gekhtman - arXiv preprint arXiv:2303.10769, 2023 - arxiv.org
We study boundaries arising from limits of ratios of transition probabilities for random walks
on relatively hyperbolic groups. We extend, as well as determine significant limitations of, a …
