GROUPOIDFEST 2008

Talks and Abstracts

Groupoidfest talks will commence on the morning of Saturday, November 22, and end at around 1 pm on Sunday, November 23.
There will be a Gfest dinner on Saturday evening (we will go somewhere nice and affordable rather than fancy).

NOTE: On Friday, November 21, at 3:00 pm, there will be a special colloquium talk at the UC Riverside math department. All Gfest participants are invited!
