Centralisers and the virtually cyclic dimension of $Out (F_{N})$

Yassine Guerch, Sam Hughes, Luis Jorge Sánchez Saldaña

We prove that the virtually cyclic (geometric) dimension of the finite index congruence subgroup $IA_{N} (3)$ of $Out (F_{N})$ is $2 N - 2$ . From this we deduce the virtua…

Commensurators of abelian subgroups and the virtually abelian dimension of mapping class groups

Rita Jiménez Rolland, Porfirio L. León Álvarez, Luis Jorge Sánchez Saldaña

Let $Mod (S)$ be the mapping class group of a compact connected orientable surface $S$ , possibly with punctures and boundary components, with negative Euler characteristic.…
