We construct several series of explicit presentations of infinite hyperbolic groups enjoying Kazhdan's property (T). Some of them are significantly shorter than the previously known shortest examples. Moreover, we show that some of those hyperbolic Kazhdan groups possess finite simple quotient groups of arbitrarily large rank; they constitute the first known specimens combining those properties. All the hyperbolic groups we consider are non-positively curved k-fold generalized triangle groups…

Tame automorphism groups of polynomial rings with property (T) and infinitely many alternating group quotients

. We construct new families of groups with property (T) and infin- itely many alternating group quotients. One of those consists of subgroups of Aut( F p [ x 1 ,...,x n ]) generated by a suitable set



Structure and Rigidity in (Gromov) Hyperbolic Groups and Discrete Groups in Rank 1 Lie Groups II

Abstract. We borrow the Jaco-Shalen-Johannson notion of characteristic sub-manifold from 3-dimensional topology to study cyclic splittings of torsion-free (Gromov) hyperbolic groups and finitely

On the Bass–Lubotzky Question about Quotients of Hyperbolic Groups

Abstract We prove at Theorem 1 that any non-elementary hyperbolic group G possesses a non-trivial finitely presented quotient Q having no non-trivial subgroups of finite indices. The theorem was

Orthogonal forms of Kac-Moody groups are acylindrically hyperbolic

We give sufficient conditions for a group acting on a geodesic metric space to be acylindrically hyperbolic and mention various applications to groups acting on CAT($0$) spaces. We prove that a group

The virtual Haken conjecture

We prove that cubulated hyperbolic groups are virtually special. The proof relies on results of Haglund and Wise which also imply that they are linear groups, and quasi-convex subgroups are

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

These notes are devoted to lattices in products of trees and related topics. They provide an introduction to the construction, by M. Burger and S. Mozes, of examples of such lattices that are simple

Strong approximation for Zariski-dense subgroups of semi-simple algebraic groups

(1.1) THEOREM. Let k be an algebraically closed field of characteristic different from 2 and 3, and G an almost simple, connected and simply connected algebraic group defined over k. Let F be a

Cubulable Kähler groups

We prove that a K\"ahler group which is cubulable, i.e. which acts properly discontinuously and cocompactly on a CAT(0) cubical complex, has a finite index subgroup isomorphic to a direct product of
