*-Combinat 2009

International Sage Workshop on Free and Practical Software for Algebraic Combinatorics

Dates: July 25-29

Location: RISC, Linz, Austria

This event will follow FPSAC'09, and be part of RISC's summer 2009.

Goals

get new users and developers on board, especially from the FPSAC community
help former MuPAD-Combinat users to switch to Sage
developers meeting

Tentative program

Saturday:
- Sage and Sage-Combinat introductory talks
- Hands on tutorials
Sunday:
- Informal Sage-Combinat lab: come work on your own problem with experts at your full disposition
- Relaxed afternoon (to recover from a long FPSAC week)
Monday-Wednesday:
- Informal Sage-Combinat lab
- Technical talks
- Short focused tutorials (see below)
- Coding sprints
- Design discussions

Preliminary list of short tutorials

Besides the main general-purpose Sage-Combinat tutorial, we will run short tutorials focused on specific features, with a (flexible) format like 10 minutes of presentation; 20 minutes of exercises. Here are some ideas. Please feel free to suggest others, especially around some features you developed yourself!

Posets (Franco?)
Words (Franco?)
Species and decomposable classes in Axiom / Aldor / Maple / MuPAD (Mike? Ralf? Martin?)
guess in Axiom / Aldor (Martin?)
Coxeter groups, crystals (Anne?)
Symmetric Functions, Non Commutative Symmetric Functions, using algebras with several basis (Jason? Nicolas?)
categories/parents/elements (Nicolas)
Implementing enriched enumerated sets, (e.g. how to enrich the partitions of 5 with a semi-groups structure) (Florent?)
Implementing new combinatorial objects (?)
Implementing new (Hopf) Algebras with bases (Florent? Nicolas?)
Sharing code with the Sage-combinat patch server
using the GenericBacktracker class to generate lattice paths and other objects (Dan Drake)?
