Strictly, if you want to make a translation surface out of this pair you have to remove the zeros of w from X and then integrate w.</p> <p>As a general reference take the book:</p> <p><a href="http://perso.univ-rennes1.fr/anton.zorich/papers_e.html" rel="nofollow">Flat surfaces (by Anton Zorich)</a> </p> <p>in collection "Frontiers in Number Theory, Physics and Geometry. Volume 1: On random matrices, zeta functions and dynamical systems'', P. Cartier; B. Julia; P. Moussa; P. Vanhove (Editors), Springer-Verlag, Berlin, 2006, 439-586.</p> http://mathoverflow.net/questions/1243/how-to-write-math-well/2092#2092 Answer by Ferran V. for How to write math well? Ferran V. 2009-10-23T14:24:30Z 2009-10-23T14:24:30Z <p>P.Halmos in <em>How to write mathematics</em> (easy to be found via your favorite www search engine) gives some nice advice. Or try Serre's exposition <em><a href="http://modular.fas.harvard.edu/edu/basic/serre/" rel="nofollow">Writing mathematics</a></em>.</p> http://mathoverflow.net/questions/1714/best-online-mathematics-videos/1897#1897 Answer by Ferran V. for Best online mathematics videos? Ferran V. 2009-10-22T17:26:54Z 2009-10-22T17:26:54Z <p>My personal favorite in Dimensions, that was mentioned before by Gerald Edgar. For a neat and clear exposition the Geom.of 3 manifolds, Poincaré conjecture, etc I recommend <a href="http://athome.harvard.edu/threemanifolds/index.html" rel="nofollow">this</a> lecture by C.McMullen. Or Das Schöne denken (hosted at the HIM in Bonn), for a good "glimpse in the world of the mathematician". Jos Leys' mathematical imagery contains some (interesting) videos and (a lot of beautiful) images. </p>
