Formerly Promised Notes...

I have uploaded the notes I made on Cahn's book and used to give a talk to my esteemed fellow students at KCL in room 102 (All hail the Emperor!). These are a work in progress and are intended to give a speedy, rather than detailed, overview of the first few chapters of Cahn. http://www.mth.kcl.ac.uk/~ppcook/
