Proposition 5.2 is wrong as stated. New and corrected version is posted.
Sorry, but such happens.

As you will see, I have posted Notes8 on the website. As usual, it is hastly written, so take it for what it is.
Notes7 is missing. It should have been about non-singular varieties, sorry for that. You have to read the corresponding section in Harsthorne's book.

I have very hastedly written up something about Bezout's theorem.
With a slightly different approach than I had on thursday. At least in my opion it is simpler–so hopefully you wil enjoy it!
Geir
As I promised during the lecture I have posted new versions of Notes4 and Notes5–as usual, take them for what they are!

The exam will take place in the week just before Easter, that is between 19. and 23. of Mars. The precise time and day depends on when sensor can come.

The exercise 3.3 in Notes 3 about the product was unintentionally too difficult; as usual, I was too quick. So I have split it in three and given hints. It is of course a little late, but better late than never. Even now it can challenging, but now it should be possible!! Sorry!
I'll finish it next Tuesday.
So new version of Notes 3 on the web.
Exercises appended to list (with some repetitions)
From Hartshorn 1.4 (that is te one I spoke about during the lecture)
From Notes 3:
3.1, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.10 and 3.11

As promised I have posted a very very preliminar verison of Notes4 on the website of the course. Take it for what it is, at least it indicates what I am going to do to morrow. Better version will follow!

A new version of Notes 3 (just small changes) on the web.

Anyhow, here are the new ones:
2.15, 2.16, 2.19,.2.20, 3.2, 3.3, 3.6 and 3.7

The lectures on Thursdays will take place from 10.15 to 14.00.
The new location is in the room "City of Gold" at Ullevål stadion.
No rooms at NAH or VB are free, so the only possibility is at he institute which p.t. is located at Ullevål stadion.
The address is: Sognsveien 77B at the second floor (=3. etasje).

Have corrected some stupid errors.
More impoertanly, exercise 2.12 has been reformulated slightly. Hopefully it is now possible to do in a reasonable way.
