Hi. I can't seem to find the notation Emb(K/F,phi_0) in D & F (or Langs Undergraduate algebra, VII, for that matter). Can you point me to a source which use this notation and cover similar material as you covered today?
Best,
Ben
You are right!
I found some notes from a number theory course at UiO. If I have time I will tex my own notes (but I do not see it as realistic before Xmas)
