I gave this course several years ago: for those who would find them useful, the notes for that course are here. I expect to follow these reasonably closely but there may be deviations from time to time. (In particular, the last 3 pages of those notes cover very interesting material which is not in the official schedule; depending on time, I may omit it or replace with something different but equally interesting.)
