New notes

I have uploaded some notes about norms, which we are going to   do to morrow.

To morrow we finish the example on page 41.

We do paragraph 8 (norms)

We skip the   paragraph  9, the last part about quadratic extensions we have done  long time ago.

Then if time allows, we start on paragraph 10 ¨C cyclotomic extensions.

Next week we finish paragraph 10, we do paragraph 11 about quadratic reciprocity. And I guess that will be what we have time to do.
