NB : There is no ¡­

NB: There is no lecture on wednesday december 16.

On friday december 17., we will do theory instead of exercises. Solutions for Ark4 are now on the net. Of course, as usual, any question is welcome.

Last friday we finished chapter 9. The paragraph called "Fractional ideals" is not part of the curriculum. In chapter 10 I will only do what is needed for chapter 11. This means the part of the paragraph called "Filtrations" starting on page 105 and ending with corollary 10.10 on page 107.
