Abstract: I will sketch the overall ideas surrounding Bauer and Furutas definition of a stable homotopy invariant - refining the usual Seiberg-Witten invariant (knowledge of which is not assumed). I will also sketch some of their re-proofs of famous theorems (many of which where first proved by Donaldson). I will then ask the audience for volunteers to fill in details of select parts of this (those parts people are most interested in) - so that we can use these talks as "fillers" for future Wednesdays where we do not have a speaker.

Alternatively, you can suggests other topics afterwards you would rather learn (more) about an we can try and go there instead.
