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 …

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 …
Dans cette thèse, on étudie des marches aléatoires induites par des actions de groupes probabilisés sur des espaces de courbure négative ou nulle. On décrit en particulier le cas …

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 …

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 …

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 …
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 …
