I made an exception here because non-discrete valuation rings are often seen as esoteric creatures and I have never heard of a course in commutative algebra in which they are taught: I would be very happy if you decided to be an exception! Incidentally this is rather strange and might be due to Grothendieck's hatred of valuation rings, which is alleged to be one of the causes of his leaving Bourbaki. Se non è vero... | |
