Week 6

I finished chapter 1 and started chapter 2, which I hope to finish next week. These chapters contain the definitions of the structure and basic tools that the rest of the course will depend on.

As problems for Tuesday I suggested Problem 4 from chapter 1 and 8 from chapter 2, but then I overlooked that 2.8 concerns concepts (Riemannian connection) that I haven't covered yet.  Hence we postpone that until later.
