24. Tensor products and a taste of Tor
🎉🎉🎉 Welcome to Algebraic Topology II 🎉🎉🎉
I hope you all enjoyed your vacation.
I'm sure you're all glad that the time for doing tedious things like skiing is over, and that instead, you can now get on with more interesting things, such as computing homology groups. 🤓
Before we can get started on the topology though, we need to cover some algebraic blabla. This lecture we did tensor products and introduced the Tor functor. Next lecture we'll explore further properties of $Tor$, then define homology with coefficients and prove the Universal Coefficients Theorem,
Anyway, here are today's notes. As usual, I'm sure they're full of typos, so please do leave comments to let me know!
