Basic information about the class
The notes Final copy of this version (except for some inessential corrections that still need to be made).

Occasionally I correct or add something to the notes without changing the numbering. If something in the printed copies of the notes that you have looks wrong, check the posted copy, and if it still looks wrong tell me.

If you want to find all the changes that have been made to the notes, search the posted copy for XXX which marks the spots.
