Property $P_{naive}$ for acylindrically hyperbolic groups

Group Theory 2020-07-20 v2 Geometric Topology

Abstract

We prove that every acylindrically hyperbolic group that has no non-trivial finite normal subgroup satisfies a strong ping pong property, the PnaiveP_{naive} property: for any finite collection of elements h1,,hkh_1, \dots, h_k, there exists another element γ1\gamma\neq 1 such that for all ii, hi,γ=hiγ\langle h_i, \gamma \rangle = \langle h_i \rangle* \langle \gamma \rangle. We also obtain that if a collection of subgroups H1,,HkH_1, \dots, H_k is a hyperbolically embedded collection, then there is γ1\gamma \neq 1 such that for all ii, Hi,γ=Hiγ\langle H_i, \gamma \rangle = H_i * \langle \gamma \rangle.
