The RIT on Geometry and Physics, a learning seminar on topics of interest to both mathematicians and physicists, will meet this semester on Thursday afternoons at 3:30 PM in room Kirwan 1311. The topic this semester is "hyperbolic band theory," about matter modeled on a lattice in hyperbolic space. A few references are:

Course credit is available for undergraduates via the course number MATH 489 and for graduate students via the course number MATH 689. (The course also counts toward the AMSC RIT requirement.) You can get 1 course credit in exchange for giving a lecture on one of the references above or a related topic. If you are interested in taking the course for credit, please contact me or one of the other organizers (Richard Wentworth, Amir Gholampour, or Jim Gates).
Because of senior job candidates Christopher Hendersonvisiting this Thursday, January 30, and Marcus Michelen visiting the following Thursday, February 6, the first meeting of the RIT won't be until Thursday, February 13.
