| Jul 2, 2012 at 12:43 | comment | added | Andrew | Thank you for your response. I will comment your answer and upper questions here. I am considering a particular diffeomorphism (up to isotopy to identity) of a surface F given by a function f: F --> F. Can I write down a presentation of this f in terms of Dehn twists? For example, given an involution x |--> -x,can this be made? | |
