Sage Days 36: p-adics in Sage

February 19-23, 2012, UC San Diego

This workshop will focus on p-adic numbers and associated structures in Sage. There will be a substantial emphasis on core structures (arithmetic, p-adic fields, extension fields, polynomials and power series, linear algebra) and in particular on fixing bugs in these. Other topics may include: p-adic special functions, p-adic L-functions, p-adic Hodge theory, p-adic cohomology and zeta functions, p-adic modular forms.

Note to participants: if you haven't already, please join the Google group sagedays36 for further announcements.

Schedule (still tentative!)

Workshop activities will be in the APM (Applied Physics and Mathematics) building, labeled 249 on this campus map. The main elevators are out of order, so follow the signs for the freight elevator (or take the stairs if you prefer). For the entirety of the workshop, we have reserved one large classroom (APM 6402) and one smaller classroom (APM 6218); during talks in one room, the other room will be available for undisturbed coding.

The UCSD-GUEST wireless network is available throughout campus; you will have to register once per day. You can also use the eduroam network if your home campus supports this.

Housing and Transportation

Except for those who made other arrangements, everyone is staying at the Clarion Del Mar Inn. To get from San Diego Airport to the hotel, if possible, you should get a ride with someone renting a car. We have a google spreadsheet to coordinate arrivals; if you don't have permission to view it e-mail David or Kiran. Feel free to call Kiran from the airport for assistance. (Note that there are three terminals at SAN: the Commuter Terminal for all flights from LAX; Terminal 1 for United, Alaska, and Southwest; and Terminal 2 for other carriers. All rental cars are offsite, reached by shuttles.) Backup options (no prebooking required) include SuperShuttle (shared vans) or taxis (cheaper than SuperShuttle for 3 or 4 people).

We'll be commuting from the hotel to the math department in a fleet of rental cars. A backup option is the 101 bus (the "Breeze"), which has stops close to both the hotel and the math department but is not very fast or frequent (and stops running at 9:30 PM). The fare is \$1.75 each way (exact change required); maps and timetables are here. If all else fails, call Yellow Taxi at 619-444-4444; a taxi from the hotel to UCSD should run no more than \$30 for up to 4 people.

Parking enforcement at UCSD is quite strict. Avoid problems by parking as follows. (See the campus map for lot locations.)

• On weekends and holidays (in this case Sunday and Monday = Presidents Day): you may park for free at any space except those marked as "reserved". The closest lots to APM are P206 and P207.

• On weekdays: The closest lot offering visitor parking is P208. Buy a permit from the pay station, park in any B (green) space, and leave the permit visible on the dashboard. After 4:30 PM, permits also become valid in the closer lots P206 or P207 except in spaces marked as "reserved".

Sustenance

There are many options for lunch within a short walk from APM. The closest ones (and their labels on the campus map):

• Pines (225), a cafeteria just west of APM in the Muir College complex.
• Roots (225), a vegetarian restaurant in the basement below Pines. Closed weekends/holidays.
• Hi Thai (293), a Thai/Asian restaurant slightly south of APM in the Student Center. Closed weekends/holidays.
• Goody's (375), a burrito/sandwich shop north of APM in the Marshall College complex.
• Price Center (911), a large food court east of APM in the central campus.

For coffee on campus, we suggest the coffee kiosk just south of the Mandeville Center (285). Other options at slightly further distances include Goody's (see above) and Espresso Roma and Perks (both in the Price Center). In case you prefer juice to coffee, there is a Jamba Juice in the Price Center.

Off campus, most food options require a car. However, from the hotel, there are numerous restaurants within walking distance along Camino del Mar.
