Sage Days 64: Algebraic Combinatorics

General Information

The goal of these Sage Days is to bring together developers in algebraic combinatorics, Lie theory and representation theory to discuss needed features and develop code. People who have coded in Sage and would like to get help getting their code integrated into Sage are also welcome to join. Any level of Sage experience is welcome, however there will not be basic (python) programming tutorials. So we encourage people who wish to participate to have an understanding of basic python (there are numerous tutorials available online and books available if you want to learn) and basic object-oriented programming (OOP for short).

We would like to point out that a combinatorics related workshop will be held at AIM the following week for people who would like to combine the two, see AIM workshop.

When & Where

March 17-20, 2015 at UC Davis.

Registration

Registration is free. We have limited funding for travel and lodging. Funding decisions will be made by December 1, 2014.

To register, e-mail either Anne (anne at math.ucdavis.edu) or Travis (tscrim at ucdavis.edu), and please indicate if you would like to apply for funding. You can also add your name to the participant list below with contact information!

Lodging

We have the following "official" conference hotels. To get the specified room rates, when making the reservation mention that you are with "Sage Days". You need to book your room before February 3, 2015 to get the special rates.

• Aggie Inn (530)-756-0352 Conference rate of $114 - 134 a night.

• Best Western University Lodge $95 a night.

There is also the following recommendation:

• Econolodge (make sure you pick the one in Davis)

If you are receiving funding, please contact Matt Silver (mtsilver at math.ucdavis.edu) to reserve a room.

Transportation

The nearest airport is Sacramento International (SAC), and are multiple ways to get to UC Davis. There is bus route 42. There is also an airport shuttle.

The two other nearby major airports are San Francisco International (SFO) and Oakland International (OAK). From both airports, a combination of BART and Amtrak can be used to get to UC Davis. In particular, there is the Capital Corridor line at either the Oakland Coliseum or Richmond BART stations.
