Today and next time

Today I did what was left of section  27, i.e. the paragraphs called "Prime fields" and "Ideal structure of F[X]". Then we did most of section 28, but not theorem 29.18.

Next wednesday, I ll do the first part of section 31, i.e. the paragraph called "Finite Extensions" – The paragraphs "Algebraically closed Fields and Algebraic Closures" and "Proof of Existens of an Algebraic closure" will not part of curriculum , we also must take section 31 out the curriculum.

Then I 'll do a short version of 45, 46 and 47. Details not yet clear.
