    • 日時:平成25年5月31日(金)16:30〜17:30

The mapping class group of an orientable surface is the group of isotopy classes of orientation-preserving self-diffeomorphisms of the surface. These groups play a central role in low dimensional topology. Therefore, its algebraic properties are of interest. After introducing a few applications and known algebraic properties, I will focus on the number of various generating sets of this group, and discuss the minimum sizes of such sets.
