GAGA Seminar

Loren Spice will continue lecturing on “Lies, and the Lying Sophus Who Grouped Them” on Wednesday, December 4 at 3:30 pm in TUC 243.

Abstract: We will discuss Lie groups from a fairly high-level perspective, based on notes of Richard Borcherds, assuming considerable prior exposure to specific concrete matrix groups. Although Borcherds’s notes are very wide-ranging, we’ll focus on results leading up to various sorts of classifications of Lie groups and Lie algebras, both with and without the assumption of reductivity, and both with and without the assumption that we are working over algebraically closed fields.

The Geometry and Geometric Analysis (GAGA) Seminar is an opportunity for geometers, topologists, and others from TCU and UT Arlington to learn about new topics of mutual interest. GAGA meets most weeks during the school year.

We keep an archive of notes from past GAGA lectures.
