AMS special session on algebraic combinatorics:

Brian Taylor and I are coorganizing an AMS special session on algebraic combinatorics at the sectional meeting to be held March 1-3, 2002 in Ann Arbor, Michigan, at the Univ. of Michigan, specifically Room 260 of Dennison Hall. (This is a change from the room we were originally assigned!) The math department is in East Hall, which (fortunately) is very close to Dennison Hall. Both buildings are a little bit below the center of this map. The Michigan math department has also made a web page for the AMS meeting with information about Ann Arbor, etc.

Below is a schedule of speakers followed by information on accomodations. The special session talks are 20-25 minutes each, including questions. The AMS web page for the conference says that Metropolitan Shuttlebus Service (734)727-1740 now provides tranportation between the Detroit airport and the University of Michigan campus for $22 per person one-way or $40 roundtrip. (This is new, so I'd suggest calling them to be sure!) Otherwise, you will face either a $40-$50 cab fare each way or need to rent a car. Also, some of the hotels below could fill up before the AMS deadlines.

Accommodations:

If the AMS hotels below are all full, there are plenty of other hotels in Ann Arbor, but many of them are far from campus. I strongly recommend getting something within walking distance of campus -- Ann Arbor buses do not run early or late enough on weekends to allow you to get to all the talks, and parking can be somewhat difficult/expensive around campus. Here is a web page listing lots of Ann Arbor hotels, but I think a large fraction of these are far from campus.

AMS conference hotel info (copied directly from AMS web page):

Participants should make their own arrangements directly with the hotel of their choice and request the AMS/Sectional Meeting discount. The AMS is not responsible for rate changes or for the quality of the accommodations. Rates do not include taxes.
