Geometry and String Theory
2022-23

This is the homepage for the UT Geometry and String Theory Seminar. At the organizational meeting we will flesh out the details of our plans for the semester. Below are some suggestions to get us started.

There is a mailing list. To subscribe, send an email to sympa@utlists.utexas.edu with subject
β€œsubscribe math-gst Your Name”.

At least for the Fall, the seminar will take place online.
