Subgroups of Lacunary Hyperbolic Groups and Free Products

20 Feb 2020 Khan Krishnendu

A finitely generated group is lacunary hyperbolic if one of its asymptotic cones is an $\mathbb{R}$-tree. In this article we give a necessary and sufficient condition on lacunary hyperbolic groups in order to be stable under free product by giving a dynamical characterization of lacunary hyperbolic groups...
