Sage Days 73 in Oaxaca, Mexico May 04-07 2016

Sage is an open source software for mathematics. This is the webpage for the Sage workshop prior to the conference Flat Surfaces and Dynamics of Moduli Space to be held in Oaxaca May 08-13. The aim is to:

The workshop started on wednesday 04 morning and ended on saturday 07. It took place at Punto Mexico Conectado @ Oaxaca in calzada Madero numero 101.

Projects

Teichmûller polynomials

people: Ferrán

The algorithm that given the (decorated) train-track algorithm produces the Teichmueller polynomial is ready!! Remains to produce automatically these graphs.

flatsurf Package(s)

people: Charles, Pat, Vincent

Build a nice Sage module for all translation surface related stuff. The aim is to

visualize Teichmueller spaces

people: Maxime, Kasra

A nice animation of a Teichmueller geodesic embedded in R3 (four time punctured sphere):

Given two complex structures on the pentagon, the first plot represents the graph of (half the logarithm of) the ratio of extremal lengths with respect to these structures, as a function on measured foliations. The next two plots are the derivative and second derivative respectively.

visualize the translation structure induced by a not so nice differential

people: Anja

Generating saddle connections in a given surface and study their statistics *efficiently*

people: Grace

Distribution of gap of saddle connection for a surface defined on a cubic field!

Computing quadratic differentials on tori

people: Charles

Using Weirstrass function one can find explicit formulas for quadratic differentials on tori
