Rips construction without unique product

Group Theory 2023-05-03 v1

Abstract

Given a finitely presented group Q,Q, we produce a short exact sequence 1NGQ11\to N \hookrightarrow G \twoheadrightarrow Q \to 1 such that GG is a torsion-free Gromov hyperbolic group without the unique product property and NN is without the unique product property and has Kazhdan's Property (T). Varying Q,Q, we show a wide diversity of concrete examples of Gromov hyperbolic groups without the unique product property. As an application, we obtain Tarski monster groups without the unique product property.
