(GST)^2 Plans and Schedule

GST^2 stands for Graduate Students Talking about Groups, Semigroups, and Topology. It's a student-run version of the GST seminar run at UNL! The goal is to be first-year friendly, accessible, and interesting. It's a great place to test-run a talk, too. 

Currently it is co-led by Kaitlin Tademy and Kathryn Van Etten, and meeting every Friday 3:00-3:30 in Avery 118. Email us at GST2@listserv.unl.edu for any questions!
