Surface mapping class group actions on 3-manifolds

Alina Al Beaini, Lei Chen, Bena Tshishiku

For each circle bundle $S^{1} \to X \to Σ_{g}$ over a surface with genus $g \geq 2$ , there is a natural surjection $π : H o m e o^{+} (X) \to M o d (Σ_{g})$ . When $X$ is the unit tangent bundle $U Σ_{g}$ , it…

Mapping class groups of exotic tori and actions by $SL_{d} (Z)$

Mauricio Bustamante, Manuel Krannich, Alexander Kupers +1

We determine for which exotic tori $T$ of dimension $d \neq = 4$ the homomorphism from the group of isotopy classes of orientation-preserving diffeomorphisms of $T$ …

Mapping class groups of circle bundles over a surface

Lei Chen, Bena Tshishiku

In this paper, we study the algebraic structure of mapping class group $M o d (X)$ of 3-manifolds $X$ that fiber as a circle bundle over a surface $S^{1} \to X \to S_{g}$ . T…
