Alg. is entitled "excellent rings", there are only two pages devoted to them there, i.e. excellent rings are defined on the next to last page of that chapter. Aha! there is a 50 page appendix that discusses them further. So this appendix seems to be mostly what is omitted from the later book. However several proofs are omitted also from this appendix and referenced instead to EGA, Bourbaki, and Nagata. This material does not appear to me to be needed say to read Hartshorne. Most of these are topics I myself have seldom encountered. | |
