Morse theory, random subgraphs, and incoherent groups

Research output: Contribution to journal › Article › peer-review

Abstract

We prove that certain polygons of finite groups have finitely generated infinite index normal subgroups, and are hence incoherent. This gives a new family of incoherent Kleinian groups. The method of proof suggests an effective approach toward related problems.
