The Twenty-Fourth Annual Geometry Festival will be held at the Mathematics Department of Stony Brook University from Friday afternoon, April 17, to Sunday noon, April 19, 2009.

Everyone is invited to the Geometry Festival, and graduate students are especially encouraged to attend.


A list of speakers at previous Geometry Festivals can be found here.


Registration will begin at 3:30pm on Friday in the basement lecture hall (S-240) of the Mathematics Building. The first talk will be at 4:30PM on Friday, followed by a wine-and-cheese reception. All remaining lectures will take place Saturday and Sunday. Continental breakfast will be served on Saturday and Sunday mornings, prior to each day's first talk. Coffee will be available in S-240 during the hours of the conference. The conference will end at noon on Sunday to allow ample time for travel home that afternoon.

At the end of the Saturday afternoon, April 18th, there will be a gathering for reminiscences of Detlef Gromoll and dedication of the common room in his honor. This will be followed by a dinner hosted by Jim and Marilyn Simons. Please let us know by April 13th if you would like to attend the dinner (venue capacity is limited).


We will try to arrange for you to receive a visitor's parking permit for campus lots, provided you request one well in advance of the festival. There should also be metered spaces available for those who forget to plan ahead.


We have reserved blocks of rooms at the following area hotels at reduced rates. All of these hotels are some distance from the conference site, but convenient shuttle bus service will be provided for the participants.

The Three Village Inn, Main Street, Stony Brook, NY (631) 751-0555. On the harbor in Stony Brook village. Scenic location, with a rural feel; about 30-min walk from the Stony Brook train station and the math department. The hotel provides shuttle service to the train 9am-6pm; Suffolk Transit Bus S76 also runs from the hotel to the train station about hourly Mo-Sa.

Holiday Inn Express, 3131 Nesconset Highway, Stony Brook, (631) 471-8000. Less charming, but more practical. Rate includes shuttle to/from Long Island's Islip-MacArthur Airport as well as the Stony Brook campus; the shuttle operates 8am-10pm.

Danford's Inn, 25 East Broadway, Port Jefferson, NY (631) 928-5200. On the harbor in Port Jefferson village. Scenic location, with a number of shops and restaurants nearby. Suffolk Transit Bus S60 runs hourly to the math department and S76 to the Stony Brook train, except for Sundays.

We recommend you make your reservations as soon as possible, as space is limited. Please mention that you are attending the Stony Brook Mathematics Department conference in order to qualify for a special reduced rate.


Participants are asked to register in advance. If you would like to have wireless internet access while on campus, please be sure to register by Wednesday, April 15.

Participants will pay for their own travel, hotel accommodations, and meals not provided by the Festival. However, substantial grants from the National Science Foundation and from Stony Brook University will make it possible for us to reimburse the expenses of a large number of graduate students, post-docs, and other qualified applicants who do not have access to travel funds from other sources. To apply for support, follow the procedure detailed below.


This Geometry Festival is supported by grants from The National Science Foundation and Stony Brook University. Substantial funds have already been set aside for the reimbursement of travel and hotel costs incurred by qualified applicants. Strong funding preference will be given to those graduate students and younger faculty to whom other funds are not available. Please check the appropriate boxes and provide the indicated information on the registration form to help us with this.

If you wish to apply for funding, please email us the following information:

  1. curriculum vitae;
  2. either
    • a list of your publications, or
    • a letter of recommendation.
  3. a statement of whether other support is available to you from the NSF and/or your own institution.
Visa holders and other international guests should be prepared to present their passports, I-94 (arrival/departure record) and other visa-related documents to festival staff if they wish to qualify for funding.

Requests for travel support will be accepted up to the time of the Festival.
