The GRASP seminar aims to be accessible to graduate students, and focuses on geometry and representation theory and their connections to mathematical physics. The organizers are Theo Johnson-Freyd and Harold Williams. The seminar meets Fridays, 11:10-12:00, in 939 Evans. We stole the name and clever acronym from the eponymous seminar at UT Austin.

If you would like to give a talk or to join the mailing list, send an e-mail to either Theo or Harold.
