Groups Generated by Powers of Dehn Twists

Hessam Hamidi-Tehrani

Published 1998-09-28Version 1

We classify groups generated by powers of 2 Dehn twists which are 1) free or 2) have no ``unexpected'' reducible elements. We give some sufficient conditions in the case of groups generated by powers of more than two twists.
