Relatively dominated representations

F Zhu - Annales de l'Institut Fourier, 2021 - numdam.org
Anosov representations give a higher-rank analogue of convex cocompactness in a rank-
one Lie group which shares many of its good geometric and dynamical properties; …

A metrizable topology on the contracting boundary of a group

C Cashen, J Mackay - Transactions of the American Mathematical Society, 2019 - ams.org
The 'contracting boundary'of a proper geodesic metric space consists of equivalence
classes of geodesic rays that behave like rays in a hyperbolic space. We introduce a …

Boundaries of Dehn fillings

D Groves, JF Manning, A Sisto - Geometry & Topology, 2019 - msp.org
We begin an investigation into the behavior of Bowditch and Gromov boundaries under the
operation of Dehn filling. In particular, we show many Dehn fillings of a toral relatively …

Notions of Anosov representation of relatively hyperbolic groups

T Wang - arXiv preprint arXiv:2309.15636, 2023 - arxiv.org
We prove that divergent, extended geometrically finite (in the sense of Weisman arXiv:
2205.07183) representations can be interpreted as restricted Anosov (in the sense of …

Hyperbolic HHS I: Factor systems and quasi-convex subgroups

D Spriano - arXiv preprint arXiv:1711.10931, 2017 - arxiv.org
In this paper we provide a procedure to obtain a non-trivial HHS structure on a hyperbolic
space. In particular, we prove that given a finite collection $\mathcal {F} $ of quasi-convex …

Simple Anosov representations of closed surface groups

N Tholozan, T Wang - arXiv preprint arXiv:2307.02934, 2023 - arxiv.org
We introduce and study\emph {simple Anosov representations} of closed hyperbolic surface
groups, analogous to Minsky's\emph {primitive stable representations} of free groups. We …

Computing JSJ decompositions of hyperbolic groups

B Barrett - Journal of Topology, 2018 - Wiley Online Library
We present an algorithm that computes Bowditch's canonical JSJ decomposition of a given
one‐ended hyperbolic group over its virtually cyclic subgroups. The algorithm works by …

Blown-up corona of relatively hyperbolic groups

T Fukaya - arXiv preprint arXiv:2402.11501, 2024 - arxiv.org
We show that under appropriate assumptions, a blown-up corona of a relatively hyperbolic
group is equivariant and the compactification of the universal space for proper action by the …

Boundaries of graphs of relatively hyperbolic groups with cyclic edge groups

R Tomar - Proceedings-Mathematical Sciences, 2022 - Springer
We prove that the fundamental group of a finite graph of convergence groups with parabolic
edge groups is a convergence group. Using this result, under some mild assumptions, we …

Homoclinic leaves, Hausdorff limits and homeomorphisms

I Biringer, C Lecuire - arXiv preprint arXiv:2310.18412, 2023 - arxiv.org
We show that except for one exceptional case, a lamination on the boundary of a 3-
dimensional handlebody H is a Hausdorff limit of meridians if and only if it is commensurable …
