Finite rigid sets and the separating curve complex

Junzhi Huang, Bena Tshishiku

For each closed surface of genus $g \geq 3$ , we find a finite subcomplex of the separating curve complex that is rigid with respect to incidence-preserving maps.

Convex-cocompact subgroups of the Goeritz group

Bena Tshishiku

We show that finitely-generated, purely pseudo-Anosov subgroups of the genus-2 Goeritz group are convex cocompact in the genus-2 mapping class group.

Symmetries of exotic aspherical space forms

Mauricio Bustamante, Bena Tshishiku

We study finite group actions on smooth manifolds of the form $M #Σ$ , where $Σ$ is an exotic $n$ -sphere and $M$ is a closed aspherical space form. We give a classification result f…
