Spring 2021 Colloquium

The colloquium meets Thursdays from 4:10 to 5:00 pm virtually. We will have at least two talks every month. Lectures last 50 minutes and are followed by a short question period. The mathematical public is cordially invited to attend. (Olga Holtz is the current Colloquium Chair.)
