Large finite group actions on surfaces: Hurwitz groups, maximal reducible and maximal handlebody groups, bounding and non-bounding actions

Bruno P. Zimmermann

We consider large finite group-actions on surfaces and discuss and compare various notions for such actions: Hurwitz actions and Hurwitz groups; maximal reducible and completely re…

A note on the Nielsen realization problem for connected sums of $S^{2} \times S^{1}$

Bruno P. Zimmermann

We consider finite group-actions on 3-manifolds $H_{g}$ obtained as the connected sum of $g$ copies of $S^{2} \times S^{1}$ , with free fundamental group $F_{g}$ of rank $g$ . We prove…
