A coarse embedding theorem for homological filling functions

Geometric Topology 2020-11-19 v2 Group Theory

Abstract

We demonstrate under appropriate finiteness conditions that a coarse embedding induces an inequality of homological Dehn functions. Applications of the main results include a characterization of what finitely presentable groups may admit a coarse embedding into a hyperbolic group of geometric dimension 22, characterizations of finitely presentable subgroups of groups with quadratic Dehn function with geometric dimension 22, and to coarse embeddings of nilpotent groups into other nilpotent groups of the same growth and into hyperbolic groups.
