Flat surfers

This is the homepage for a reading group I organize on flat surfaces, moduli spaces, and billiards.

Summer 2020 schedule

All meetings will happen on Wednesdays at noon Eastern time. We’ll use the Zoom meeting ID 993 7044 2086; the password is what you call a locus of abelian differentials with fixed orders of zeroes (no caps, ends with m).

If you have any questions or want to get on the mailing list, send me an email.
