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.

- 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)?
