Mackey functors in (naïve) equivariant homotopy theory

I started writing this series of posts almost exactly a year ago, but never got around to completing part 4. The existing parts can be read independently of part 4 though so I’d rather post them here now than keep them private forever. I mean, I’d rather post them and also post part 4, but you get the point.

• Part 0: Background & motivating question
• Part 1: Where do transfers come from?
• Part 2: Introducing Mackey functors
• Part 3: Doing algebra in Mackey functors
• Part 4: Finding counterexamples - Coming soon!
