Isoperimetric behavior of generalized Stallings-Bieri groups

Group Theory 2025-09-15 v1

Abstract

We introduce the notion of nn-split for an epimorphism from a group to a finite rank free abelian group. This is used to provide bounds for the Dehn functions of certain coabelian subgroups of direct products of finitely presented groups. Such subgroups include and significantly generalize the Stallings-Bieri groups.
