Acylindrically hyperbolic groups with exotic properties

Abstract

We prove that every countable family of countable acylindrically hyperbolic groups has a common finitely generated acylindrically hyperbolic quotient. As an application, we obtain an acylindrically hyperbolic group QQ with strong fixed point properties: QQ has property FLpFL^p for all p[1,+)p\in [1, +\infty), and every action of QQ on a finite dimensional contractible topological space has a fixed point. In addition, QQ has other properties which are rather unusual for groups exhibiting "hyperbolic-like" behaviour. E.g., QQ is not uniformly non-amenable and has finite generating sets with arbitrary large balls consisting of torsion elements.
