[Binghamton Geometry Topology Seminar] Seminar This Week

[Cary Malkiewich]

Hi everyone,

A quick reminder about coffee and seminar today! If this is your first zoom
meeting of the day, set aside a little time to figure out if your password
still works or if you have to change it, there's been a bit of trouble with
such things this morning.

Best,
Cary
