CUNY Geometry and Topology Seminar

2018 — 2019

Unless a change is noted below, the CUNY Geometry and Topology Seminar takes place at 4:15pm on Tuesdays in Room 6496 (note we are in a different room than usual this semester!) of the Graduate Center, located at 365 Fifth Avenue across the street from the Empire State Building. All are welcome.
