Title: Minimal generation of spin mapping class groups

Abstract: Given a spin structure s on a closed oriented surface S, the spin mapping class group Mod(S,s) is the subgroup of Mod(S) stabilizing s. These groups are intimately related to the spin geometry of 3- and 4-manifolds. In this talk, we will discuss our results on generating Mod(S,s) with minimal number of generators, including some generalisations to r-spin groups.
