Tuesday Aug 20

Today I   did parts of  section 2 in the book, Integral dependence.

I 'll do example 1, 2 and 3 on Thursday. We postpone 2.5.

I ll prove that being integrally closed is a local property.

Then I prefer  to speak about fractional ideals (i.e. first part of section 4) before we start on section 3 with DVRs and Dedekind rings.

We have permanently moved the lecture on wednesday to thursday at 14.15 to 16.00. Room will come.
