On stable commutator lengths of Dehn twists along separating curves

Naoyuki Monden, Kazuya Yoshihara

Published 2016-06-28Version 1

We give new upper bounds on the stable commutator lengths of Dehn twists along separating curves in the mapping class group of a closed oriented surface. The estimates of these upper bounds are $O(1/g)$, where $g$ is the genus of the surface.
