Hierarchical hyperbolicity of hyperbolic-2-decomposable groups

Bruno Robbio, Davide Spriano

Let G be a graph of hyperbolic groups with 2-ended edge groups. We show that G is hierarchically hyperbolic if and only if G has no distorted infinite cyclic subgroup. More precise…

A refined combination theorem for hierarchically hyperbolic groups

Federico Berlai, Bruno Robbio

In this work, we are concerned with hierarchically hyperbolic spaces and hierarchically hyperbolic groups. Our main result is a wide generalization of a combination theorem of Behr…
