For every group $G$, we introduce the set of hyperbolic structures on $G$, denoted $\mathcal{H}(G)$, which consists of equivalence classes of (possibly infinite) generating sets of $G$ such that the corresponding Cayley graph is hyperbolic; two generating sets of $G$ are equivalent if the corresponding word metrics on $G$ are bi-Lipschitz equivalent. Alternatively, one can define hyperbolic structures in terms of cobounded $G$-actions on hyperbolic spaces. We are especially interested in the… 
Actions of small cancellation groups on hyperbolic spaces
We generalize Gruber–Sisto’s construction of the coned-off graph of a small cancellation group to build a partially ordered set $${\mathcal {TC}}$$ TC of cobounded actions of a given small

Acylindrical hyperbolicity of groups acting on quasi-median graphs and equations in graph products
In this paper we study group actions on quasi-median graphs, or 'CAT(0) prism complexes', generalising the notion of CAT(0) cube complexes. We consider hyperplanes in a quasi-median graph $X$ and

Acylindrically hyperbolic groups and their quasi-isometrically embedded subgroups
We abstract the notion of an A/QI triple from a number of examples in geometric group theory. Such a triple (G,X,H) consists of a group G acting on a Gromov hyperbolic space X, acylindrically along a
Largest hyperbolic actions and quasi-parabolic actions in groups
The set of equivalence classes of cobounded actions of a group on different hyperbolic metric spaces carries a natural partial order. The resulting poset thus gives rise to a notion of the “best”
Acylindrical Actions for Two-Dimensional Artin Groups of Hyperbolic Type
For a two-dimensional Artin group $A$ whose associated Coxeter group is hyperbolic, we prove that the action of $A$ on the hyperbolic space obtained by coning off certain subcomplexes of its modified
Random walks and quasi‐convexity in acylindrically hyperbolic groups
Arzhantseva proved that every infinite‐index quasi‐convex subgroup H of a torsion‐free hyperbolic group G is a free factor in a larger quasi‐convex subgroup of G . We give a probabilistic
Equivariant hierarchically hyperbolic structures for 3-manifold groups via quasimorphisms
. Behrstock, Hagen, and Sisto classified 3-manifold groups admitting a hierarchically hyperbolic space structure. However, these structures were not always equivariant with respect to the group. In

Hyperbolically embedded subgroups and rotating families in groups acting on hyperbolic spaces
We introduce and study the notions of hyperbolically embedded and very rotating families of subgroups. The former notion can be thought of as a generalization of the peripheral structure of a
Tight geodesics in the curve complex
The curve graph, $\mathcal{G}$, associated to a compact surface Σ is the 1-skeleton of the curve complex defined by Harvey. Masur and Minsky showed that this graph is hyperbolic and defined the
Acylindrical accessibility for groups
Abstract.We define the notion of acylindrical graph of groups of a group. We bound the combinatorics of these graphs of groups for f.g. freely indecomposable groups. Our arguments imply the
Not all finitely generated groups have universal acylindrical actions
The class of acylindrically hyperbolic groups, which are groups that admit a certain type of non-elementary action on a hyperbolic space, contains many interesting groups such as non-exceptional

We shall state the main result of this paper in terms of group actions on simplicial trees. Suppose that a group G acts simplicially on a tree T without inversions. For brevity we say that Tis a
Acylindrically hyperbolic groups
We say that a group $G$ is acylindrically hyperbolic if it admits a non-elementary acylindrical action on a hyperbolic space. We prove that the class of acylindrically hyperbolic groups coincides
Induced quasicocycles on groups with hyperbolically embedded subgroups
Let G be a group, H a hyperbolically embedded subgroup of G , V a normed G ‐module, U an H ‐invariant submodule of V . We propose a general construction which allows to extend 1‐quasicocycles on H
Commensurating endomorphisms of acylindrically hyperbolic groups and applications
An endomorphism ' of a group G is said to be commensurating, if for every g 2 G some non-zero power of '(g) is conjugate to a non-zero power of g. Given an acylindrically hyperbolic group G, we show

An automorphism of a group G is normal if it fixes every normal subgroup of G setwise. We give an algebraic description of normal automorphisms of relatively hyperbolic groups. In particular, we
