If you are averse to reading French, Magalit and Kim have translated it into English ( Work of Thurston). Exposes 3 and 4 are the real stuff. | |

| Mar 14, 2013 at 17:50 | comment | added | Mariano Suárez-Álvarez | (My comment refers to orientable surfaces, as well!, as otherwise there are no signed intersection numbers to get us started) | |
| Mar 14, 2013 at 17:43 | comment | added | maproom | Did you omit the word "orientable" from your conjecture? It's false as it stands. | |

| Mar 14, 2013 at 17:42 | comment | added | Mariano Suárez-Álvarez | Counting signed intersections of curves gives a symplectic form on the first homology group of a closed surface. In particular, in such a surface two homologous curves never intersect transversally in exactly one point. | |
