Last week, I forgot to send out a review of our meeting. I'll review it here, as well as the most recent meeting.

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.

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.

Read section 1.3, which applies Groups to rigid bodies. Work on the examples, and bring any questions you have!

Have a good weekend,
