Pseudo-Anosov dilatations and the Johnson filtration

Justin Malestein, Andrew Putman

Published 2013-07-23, updated 2015-02-02Version 3

Answering a question of Farb-Leininger-Margalit, we give explicit lower bounds for the dilatations of pseudo-Anosov mapping classes lying in the kth term of the Johnson filtration of the mapping class group.
