In this video we explore a connection between norm and trace introduced in the last lecture and the Galois conjugates of an element. These results will be useful in showing that rings of integers are finitely generated Abelian groups. In particular for showing that the trace form is non degenerate.
This is section 2.5 in Milne's notes on algebraic number theory.
