One other important point:

I’ve been having a rather exasperating 10 days trying to get BT to activate my broadband service in a new house, sadly unsuccessfully. So I may not be able to get to email questions until Monday afternoon. The people who intended to send them could also avail themselves of the special office hour.

I thought I would post a short email exchange, just in case other people are confused by this issue as well.

Email:

hi, this is where the confusion arose as you mention some proofs specifically but at the bottom where it says “Needless to say, it is assumed that you will have a full
understanding of the material surrounding the results listed above, especially the definitions and the examples.” does this include the proofs of the theorems?

>> do we need to know the proofs that are in the online notes but not in the
>> class notes?

The answer to the last question is: Yes, of course you need to know the proofs. The paragraph quoted was put in to emphasize that you need to know *more* than the proofs. The obvious intention was to discourage people from pure memorization, which has been a topic of discussion since I taught the course last year. Let me once again refer people to the the posts on the blog surrounding last year’s exam. The exchange reproduced above seems to illustrate once again a tendency to indulge in a `minimal reading’ of requirements. Be careful. to spell it out once more, what is meant is:

`You need to know the proofs and understand them fully. This means you need *also* to understand the material surrounding the theorems and their proofs.’
