Directions: see here. The Long Island Rail Road schedule can be searched here and is posted here.

Wireless Internet Access: Wireless internet access in the Simons Center for Geometry and Physics, and most buildings on campus, is available via Wolfienet Guest, or via eduroam.

Conference Hotel: The participants will be staying at Danfords Hotel in Port Jefferson. There will a shuttle bus to and from the hotel. 

Transportation: There will be a shuttle bus to and from the hotel, at the following times:


Campus → Danfords: 6:15pm and 7:00pm


Danfords → Campus: 7:45am and 8:30am 

Campus → Danfords: 5:45pm and 6:30pm


Danfords → Campus: 7:45am and 8:30am

Each bus can only seat 14 people. If you do not have a car, please try to get a ride from someone who does,  and plan to use the shuttle only as a last resort.

Parking: The main parking lot on Stony Brook's campus available for conference participants is the "H lot"; the large lot near the Earth and Space Sciences building.  You can find it in the middle of the right side of B4 on the following parking map, marked "Lot 13".  Parking in this lot is free and permitted to all on Friday after 4pm and all day Saturday and Sunday.  There are also a limited number of spots available in the parking lot immediately adjoining the Simons Center for Geometry and Physics, which requires an access code for entry.  Please contact the organizers if you are interested in parking in one of these spots.

Financial support: We will try to cover travel costs for everyone (excluding air fares), with preference given to junior participants. Graduate students applying to participate in their first AGNES should ask their advisor to send a short e-mail of support (one paragraph) to one of the organizers.

About AGNES: AGNES is a series of weekend workshops in algebraic geometry. One of our goals is to introduce graduate students to a broad spectrum of current research in algebraic geometry. AGNES is held twice a year at the participating universities in the Northeast.
