Tentative list of themes
A list of topics for Sage days 57. Participants, please edit!
Import the old Sage-Combinat patches as git branch
- Nicolas
Review all tickets waiting on trac :-)
There are around 250 tickets waiting on trac for a reviewer ... solution: a ticket a day! (18 dev, 5 days we should get 90 tickets)
Documentation
Brainstorm about the refactoring of the index of the combinatorics section of the reference manual #13605
- Sam, Florent, Nicolas, Sébastien, Charles
- Splitting the reference/combinat document in subdocuments
- Florent,
- Finish migrating the collection of Sage-Combinat thematic tutorials as git branches
- Nicolas, Vincent, Tomer
- Proofread and merge more thematic tutorials
- Sam, Vincent, Nicolas, Thierry
Coxeter groups
Jean-Philippe and Vivien implemented a framework for working with infinite coxeter groups, in particular to explore the geometric representation, limit roots, ... The goal is to start merging this with the existing root system stuff in Sage.

Automata and rational languages
- Design discussion
- Thierry, Vincent, Nicolas, Sébastien, Florent, Jean-Baptiste, Adrien, Matthieu
Improving the situation
- Thierry, Vincent, Sébastien, Matthieu
Languages
By language we simply mean a set of finite words (rational language, D0L-system, ...). The scope ranges from combinatorics and algebra to discrete dynamical systems. Sage capabilities is currently restricted to combinatorics on single word and do not focus on structure of certain subset. We aim to implement an abstract and easy to reuse infrastructure for languages.

Might be too big a task for this week. But we could discuss the strategy.
Translation surfaces
A translation surface is a geometric and dynamical objects that can be defined from gluing polygons by translation. It is interesting from geometric and dynamical point of vue. Many computations are possible !
- interested
- Vincent
- Samuel
- Thierry
- Charles
- todo
- better datastructure for permutations
- include Charles Fougeron's code into Sage (computation of Lyapunov exponents, decomposition of the Hodge bundle)
- datastructure for translation surfaces
Categories
Finish #10963, brainstorm the follow ups.

- Nicolas

- Florent
Polyhedra over number fields
- interested
- Volker
- Vincent
- Jean-Philippe
Tensors on free modules
- interested
- Eric
- todo
implement tensor products of generic free modules and the associated tensor algebra (by generic it is meant without any privileged basis)
Refactor continued fractions
- interested
- Thierry
- Vincent
- Luca
todo: see #14567
Dynamical systems simulation (statistics of orbits)
- interested
- Thierry
- Sébastien

on-line db for Sage worksheets and other ressources

Monday Afternoon
Checkout Mike's and ... patches about lazy power series

Real numbers
There are many ways to represent real numbers:
- rational numbers
- algebraic numbers
- expansions in a given basis
- continued fractions (and generalizations)
- symbolic expressions (involving transcendental functions like cos, exp, pi, ...)
- ...
But Sage currently has no bridge between them...
Refactor Elliptic curves and morphisms
See #12880 (and also problem with scheme morphisms #15378, maybe also that SchemeMorphism currently does not inherit from !Morphisn, see the description of #14711)
