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

Registration

Registration is free, but please register on: http://www.conferences.jku.at/riscsummer2009/e2570/index_eng.html.

Very convenient and reasonably priced rooms are available for reservation from the same site, but may run out. Register early!

Prerequisites

All attendees are expected to have Sage >= 4.1 and the Sage-Combinat patches installed on their laptops. If you do not plan to bring a laptop, please contact the organizers, and we will have a terminal setup for you. Please come see us for help during FPSAC if you encounter any problem!

Sage 4.1 will be available shortly from: http://www.sagemath.org/download.html

See http://wiki.sagemath.org/combinat/MercurialStepByStep for the installation instructions of Sage-Combinat. On UNIX/Mac, it boils down to running the following command in a terminal:

sage -combinat install

T-Shirts

If you would like to get the T-Shirt for this workshop (~$10), please write the size below before July 11th. Here is the current design (suggestions welcome): front-nt.png back-nt-2.png

And if you wonder about the meaning: Sage is the powerful propeller allowing us to soar high to our Castle in the Sky. Our hope is that in return our scouting will help drive the car to new horizons.

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!

Symmetric Functions, Non Commutative Symmetric Functions, using algebras with several basis (Jason? Nicolas?)
Implementing enriched enumerated sets, (e.g. how to enrich the partitions of 5 with a semi-groups structure) (Florent?)
Implementing new combinatorial objects (?)
