About WAGS
WAGS is a biannual meeting of algebraic geometers in the western half of the United States and Canada that traces its origins back to the Utah-UCLA Algebraic Geometry Seminar started in 1989. Long term planning for WAGS is currently being organized by Aaron Bertram, Sebastian Casalaina-Martin, Renzo Cavalieri, Sándor Kovács, Ravi Vakil, and Bianca Viray. For more information about WAGS, please visit www.wagsymposium.org.


We hope to broaden the community of algebraic geometers. All are welcome to attend. We especially encourage participation from women and members of groups traditionally under-represented in mathematics.


The meeting will be held at San Francisco State University.  It is hosted and organized by the SFSU Math Department.  Lectures will take place in Science 201, which you can locate on the following campus map, or you can find here on on Google maps.

Registration and Financial Assistance

Registered Participants

WAGS is partially supported by the National Science Foundation and by the Department of Mathematics and the College of Science and Engineering at San Francisco State University; if you need funding, please apply when you register.  The registration deadline for guaranteed funding has passed, but there may be additional funding available.

We ask that all participants fill out the registration form whether or not financial assistance is being requested; you must fill out both forms in order to be reimbursed:

Fort Collins, CO 80523-1874

If you are not a US citizen or permanent resident, you may receive an email from CSU (Colorado State University) requesting additional information. Please keep an eye out for it.

Please help us to keep organized by mailing your reimbursement claims by March 31, 2018. We may run into trouble allocating funds for late submissions!


Participants other than speakers are required to book their own accommodations.  Because funds for reimbursement are limited, we encourage everyone to be mindful of the price of their accommodations in order to make it more likely that they can be fully reimbursed.  (We will contact participants once registration has closed to confirm the exact cap on reimbursable expenses.)

One suggested option is for participants to share a double room in a hotel such as the following:

Nontraditional hospitality services (such as Airbnb) also provide an alternative that is often cheaper and more readily accessible to the university than many traditional hotels.  When booking any accommodation, we suggest looking near the Market Street corridor (neighborhoods such as the Castro, the northern end of the Mission District, etc.), which is adjacent to public transportation both to/from the airport and to/from the university.  Alternatively, West Portal and the southern end of the Sunset District are pleasant neighborhoods closer to campus but somewhat farther from the sights of the city.

The closest airport to SFSU is the San Francisco International Airport (airport code SFO). It is served by almost all major domestic and international airlines.

Getting from the airport to campus or San Francisco:  From SFO, take any BART train headed toward Downtown San Francisco (not toward Millbrae).  If you're headed directly to campus, get off at Daly City and then take the 28 bus (free transfer from BART).

Getting to campus by car:  Directions from SFO can be found here and directions from other places can be found here.

Local transportation in San Francisco:  You can get around San Francisco using the BART, Muni trains, and Muni buses.  You can pay pay for any of these using a Clipper card (available for $3 at Walgreens).  You can also buy a single-use ticket for BART at any station, while for Muni trains, you can buy a single-use ticket at some stations; if you board a Muni train or bus without a ticket, you'll need to pay cash ($2.25, exact change only) on board.

Getting from San Francisco to campus on public transportation:  Depending on where you're coming from, you can get to SFSU by different modes of public transportation.  For example, you can take the BART to Daly City and then take the 28 bus (free transfer).  The Muni line M train and the Muni buses 17, 18, 28, 29, and 57 also all stop at the SFSU campus.  More information on getting to campus is listed here.


Breakfast (bagels and coffee) will be served on Saturday and Sunday mornings, and a catered lunch will be served on Saturday.  Limited dining options are also available at Stonestown Galleria, a mall adjacent to SFSU.  There are, of course, many other dining possibilities throughout the city, and we encourage participants to ride the Muni to one of San Francisco's many neighborhoods and get a taste of the city for lunch on Sunday.

On Saturday evening, there will be a reception at SOMA StrEat Food Park.  We have space reserved there from 6-8pm, but arrive earlier if you'd like to beat the lines.
