Fixed subgroups and computation of auto-fixed closures in free-abelian times free groups

Mallika Roy, Enric Ventura

The classical result by Dyer--Scott about fixed subgroups of finite order automorphisms of $F_{n}$ being free factors of $F_{n}$ is no longer true in $Z^{m} \times F_{n}$ . Within this more…

Degrees of compression and inertia for free-abelian times free groups

Mallika Roy, Enric Ventura

We introduce the concepts of degree of inertia, $di_{G} (H)$ , and degree of compression, $dc_{G} (H)$ , of a finitely generated subgroup $H$ of a given group $G$ . For the ca…
