Yesterday I did the first ¡­

Yesterday I did the first paragraph in chapter 5, called Integral Dependence. To morrow I'll do the going up theorem. I'll state the going down theorem, but not give the proof. And for the moment we skip the whole paragraph called Valuation Rings (may be we need a small part of it later, but in case, we do it then.)

What we skip is of course not part of the curriculum.
