The Torsion Generating Set Of The Dehn Twist Subgroups Of Non-orientable Surfaces
Abstract
Let Ng be the non-orientable surface with genus g, MCG(Ng) be the mapping class group of Ng, T(Ng) be the index 2 subgroup generated by all Dehn twists of MCG(Ng). We prove that for odd genus, T(Ng) can be generated by three elements of finite orders.
