If you are using Mac OS X, the computer might complain with `could not fetch URL ...`. In that situation, you can try the two following solutions 1. You do have Xcode installed in which case you can recompile the Python shipped with Sage with SSL support with {{{ }}} 2. The alternative to option 1 is to download each package independently: * [[https://files.pythonhosted.org/packages/52/8d/9d27f127f159ac58f31a318c36a633d992b5f2430f0624a01910e3c1f5b6/surface_dynamics-0.4.0.tar.gz|surface_dynamics-0.4.0.tar.gz]] * and need to download each packages independently |
Sage Days 96
Sage days 96 to be held at the Fields Institute for the program Teichmüller Theory and its Connections to Geometry, Topology and Dynamics. The schedule is available on the Fields website. This wiki page will be updated with all documents relative to the workshop (worksheets, tutorials, demos, nice pictures, etc).
In order to assist to the workshop you are asked to come with your laptop (though you are also welcome without laptop). It would also be great if you could make sure that Sage is installed on it (see "Sage Installation" below).
Worksheets
Introduction with the picture S_2_1.svg to be downloaded in the same folder (the worksheet is also available as intro.en.rst and intro.en.pdf)

Sage Installation
The installation procedure depends on your operating system:
Ubuntu (versions >= 18.04) and archlinux: install the packages sagemath and sagemath-jupyter
gentoo: you can give a try to sage on gentoo
all other systems (GNU/Linux, OSX, Windows): go to the main SageMath website, go to the download section, choose a download server close to your location and download the Sage binary that corresponds to your operating system.
If you run GNU/Linux or OSX you can also try to compile the software from sources. The procedure is described in the documentation.
Installing flipper, snappy, flatsurf and surface_dynamics
These packages are installed through pip. Depending how you did install Sage you might run in different kind of complications.
- To install flipper, it should work out of the box with the command line (if you do not know how to open a command line, ask one of the organizer)
$ sage -pip install flipper --user
If the above command does not work you are in trouble, if you are using MAc OS X, see below, otherwise ask Vincent. If it does work, go to next step.
- To install surface_dynamics and snappy you need a working version of gcc and g++ (that should be the case for most of you). The commands are similar
$ sage -pip install surface_dynamics --user $ sage -pip install snappy --user
Lastly, to install flatsurf, look at the instructions at https://github.com/videlec/sage-flatsurf
If you are using Mac OS X, the computer might complain with could not fetch URL .... In that situation, you can try the two following solutions
- You do have Xcode installed in which case you can recompile the Python shipped with Sage with SSL support with
$ sage -i openssl $ sage -f python2
- The alternative to option 1 is to download each package independently: and need to download each packages independently
