Following a long tradition of similar workshops, the Sage days 100 workshop will take place in Bonn Germany, July 22nd - July 27th. It welcomes anyone who wishes to work with SageMath, from complete beginners to advanced developers. It will consist of tutorials, participant presentations and mostly free time to let participants work on their mathematical programming projects and get helped from more advanced users. The precise schedule of the workshop will be decided at the begining of the workshop and adapted according to the participant needs.

The afternoon of Wednesday 24th will be dedicated to a SageMath presentation at Max-Planck Institut (for students, PhD students, postdocs and professors). If you wish to be involved in this presentation, contact the organizer.

Schedule

• Begining of the workshop Monday 22nd
  • 9:30 - 10:00 welcome coffee

  • 10:00 - 10:30 A SageMath and sage days panorama (by V. Delecroix)

Broad mathematical thematics

Combinatorics, geometry and dynamics on real surfaces (complex curves). Here is a non-exhaustive list

• moduli space of curves, differentials, spin structures
• enumerative geometry, integral points in polytopes and (quasi-)modular forms
• geometry and dynamics of flat and hyperbolic surfaces
• braid groups, mapping class groups

Relevant Sage packages

• admcycles: tautological ring on M_{g,n} (Aaron Pixton, Johannes Schmitt, Jason van Zelm)

• snappy: 3-dim hyperbolic manifolds (Marc Culler, Nathan Dunfield, and Matthias Goerner)

• veerer: train-tracks and veering triangulations (Vincent Delecroix)

• surface_dynamics: translation surfaces (Vincent Delecroix)

• flipper: mapping class group (via flips in triangulation) (Mark Bell)

• curver: mapping class group (via curve complex) (Mark Bell)

• sage-train-track: free group automorphisms (Thierry Coulbois)

We will have 20 min presentations of each package emphasizing:

• What the package is useful for?
• What should I do if I want to use the package? ie, installation and first steps tutorials
• What is currently under active development?
• Wishlist features / possible research experimentations (with the hope that more people get involved)
