Thursday 22 Aug

To day I finished the section about integral dependence.

I did the basics about fractional ideals.

I gave an example of a non-invertible ideal, and calculated the integral elements in the quadratic number fields.

Next week we start on DVRs and Dedekind rings.

I have posted two small notes, one in Norwegian with some basic algebra, and one in English about Dedekind rings.
