Columbia Geometric Topology Seminar

Spring 2008

Unless a change is noted below, the Columbia Geometric Topology Seminar takes place Fridays in 520 Mathematics at 2:15PM, with occasional overflows to Friday at 10AM. All are welcome. We usually meet for lunch at 11:45AM.

There is an announcement list for the seminar.
