How to get a Dehn-twist presentation of a periodic map of a Riemann surface?
up vote 9 down vote favorite
Let $f:S\to S$ be a given periodic map of order $n$, and $(m_i,\lambda_i, \sigma_i)$ be the valency of the multiple point $p_i$ of $f$ ( $i=1,\cdots,r$ ).
A classical result says such $f$ is isotopic to a product ... | {"url":"http://mathoverflow.net/questions/30588/how-to-get-a-dehn-twist-presentation-of-a-periodic-map-of-a-riemann-surface","timestamp":"2014-04-16T07:33:26Z","content_type":null,"content_length":"53659","record_id":"<urn:uuid:0f3d3ba0-937f-44ef-a45a-fd59f98b80aa>","cc-path":"CC-MAIN-2014-15/segments/1397609521558.37/... |

Trig Waves question ???
Plain old cosx has a period of 2π. The variable (t) inside of cos is multiplied by 5, which compresses the period. So, the answer is 2π/5
The shift is the quantity subtracted from the variable inside cos. It seems that the shift is divided by the coefficient of t, giving 3π/10.
