Updated lecture notes. (Last updated: May 12, 2011).
The lecture notes by Wendelin Werner provide further insight and will also be relied upon.
Example sheet 1 is available here. There will be an example class on Monday, 28th February at 4pm in MR12.
Deadline for handing in work: same day 9am in my pigeonhole.
Note that the second half of question 10 is hard, and you should not attempt it.
Example Sheet 2 is available here. There was an example class after the Easter break. This version has a few typos corrected.
The last two questions are optional and for culture only.
