Chapter III

http://sites.google.com/site/alggeom/

Recently put up solutions to some of the exercises in Chapter III. More explicitly, there are solutions to:

2: 2, 3, 4, 5, 6
3: 1, 2, 3, 5, 7, 8
4: 1, 3, 5, 6, 7, 9, 11
5: 1, 4, 10
6: 1, 3, 4, 5, 6, 7, 8, 9
7: 3
8: 1, 2, 3
9: 1, 2, 7, 9

There are also some partial solutions to some of the other problems in Chapter III.

It also occurred to me that it would be more useful to have a list of the problems that I have put up solutions for, rather than those that I haven't. So here is the list of solutions that should be available at http://sites.google.com/site/alggeom/ for Chapter II:

1: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22
2: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 16, 17, 18, 19
3: 1, 2, 3, 4, 5, 6, 7, 9, 10, 13, 14, 16, 17, 18
4: 1, 2, 3, 4, 6, 8, 9
5: 2, 3, 4, 5, 6, 7, 8, 9, 10, 14, 15, 16
6: 1, 4, 11
7: 1, 2, 4, 5, 6, 7, 8, 9, 12
8: 1, 2, 3, 5, 6, 7, 8

Update

Added Section 8.

Made a list of the exercises that haven't yet been done (below).

I've almost officially lost interest in pushing these further towards completion. There are a few exercises (although not as many as I'd like) that I've almost finished, or know how to do but am too lazy to tex them up, so if there are any of these that other people are having trouble with, a comment might be just what is needed to convince me to write them up and post them.

Welcome

This is not really a blog, but a place to post my attempts at solutions to Hartshorne's Algebraic Geometry that hopefully will encourage discussion, comments, suggestions, and corrections.

I was attempting to do completely all of the second Chapter, and may still reach this goal. The progress so far can be reached here:
