Isoperimetric behavior of generalized Stallings-Bieri groups
Published 12 Sep 2025 in math.GR | (2509.09939v1)
Abstract: We introduce the notion of $n$-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.
