Following the success of last semester's undergraduate seminar on Coxeter groups and Hecke algebras, we will be running another undergraduate seminar this semester on a slightly different theme: Lie Groups in Physics. The goal of the seminar is to help bridge the gap between pure mathematics and (mathematical) physics, both pedagogically and socially. As such, we welcome students from both the mathematics and physics cohorts from 2nd year onwards, though the talks will be aimed at the 3rd year level. The seminar should (hopefully!) be of interest to students who have studied or are studying Algebra, Quantum Physics/Systems, Methods of Mathematical Physics, Electrodynamics, Geometry, Theoretical Physics, and so on. Talks will be for 100 minutes with a break in the middle. Participants will prepare their presentations under the guidance of one expert or another, and give a practice talk in advance. Great emphasis is put on clear and compelling exposition.

This seminar is coorganized by Anas Rahman, Matthew Spong, Adrian Putra, Gufang Zhao, and Srivatsa Badariprasad. Feel free to contact either of them or Nora Ganter for further details.

To be put on the email list for this seminar, contact aarahman@student.unimelb.edu.au

The seminar will be meeting weekly throughout the semester on Mondays 12:00 to 2:00 in room 107, Peter Hall Building.
