Hello all, Last week, I forgot to send out a review of our meeting. I'll review it here, as well as the most recent meeting. *Last Week, 11/06:* We read through section 1.1, focused on manifolds. We addressed questions about the requirements, definitions, and properties for these structures, and worked out some examples. *This Week, 11/13:* We read through section 1.2, covering Groups. We talked about the distinction between left and right actions, and worked an example showing the difference. We provided intuitive examples illustrating direct/semi-direct products, commutativity, and the commutator of two group actions. *Next Week, 11/20:* Read section 1.3, which applies Groups to rigid bodies. Work on the examples, and bring any questions you have! Have a good weekend, Capprin Bass Oregon State University basscap@oregonstate.edu
