Sophex is a seminar in the UT math department specifically for first and second years to give talks, attend talks by their peers, and interact in a friendly environment. If you would like to be added to the seminar mailing list or are interested in giving a talk contact Kai Nakamura (kainakamura@utexas.edu).
We meet Fridays at 4 pm in PMA 12.104.
