Sublinearly Morse Boundary of CAT(0) admissible groups
Hoang Thanh Nguyen, Yulan Qing
We show that if G is an admissible group acting geometrically on a CAT(0) space X, then G is a hierarchically hyperbolic space and with mild assumptions the sublinearly-Morse bound…
Big mapping class groups with hyperbolic actions: classification and applications
Camille Horbez, Yulan Qing, Kasra Rafi
We address the question of determining which mapping class groups of infinite-type surfaces admit nonelementary continuous actions on hyperbolic spaces. More precisely, let be…
Geometry of right-angled Coxeter groups on the Croke-Kleiner spaces
Yulan Qing
In this paper we study the right-angled Coxeter groups that acts geometrically on the Salvetti complex of a certain right-angled Artin group, which we refer to as Croke-Kleiner spa…
Dilatation of outer automorphisms of Right-angled Artin Groups
Corey Bregman, Yulan Qing
We study the dilatation of outer automorphisms of right-angled Artin groups. Given a right-angled Artin group defined on a simplicial graph: and an a…
Excursions of generic geodesics in right-angled Artin groups and graph products
Yulan Qing, Giulio Tiozzo
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 d…
Quasi-geodesics in Out(F_n) and their shadows in sub-factors
Yulan Qing, Kasra Rafi
We study the behaviour of quasi-geodesics in Out(F_n). Given an element f in Out(F_n) there are several natural paths connecting the origin to f in Out(F_n); for example, paths ass…
