Sang-hyun Kim: Optimal regularity of mapping class group actions on the circle
Abstract: We prove that for each finite index subgroup H of the mapping class group of a closed hyperbolic surface, and for each real number r greater than 1 there does not exist a faithful C^r-action (in Hölder's sense) of H on a circle. For this, we partially determine the optimal regu
