“More on free resolutions”
I’m going to tell you about the things that Ty told you I will tell you about. Specifically, for an R-module M, any two free resolutions of M are equivalent, if you choose a strange definition of ’equivalent’ ( the definition being homotopy equivalent). Furthermore, free resolutions always exist. This will involve a look at certain mythical creatures called projective modules. I may also talk about some tensor product stuff.
