Let $\zeta$ be one of $\{\zeta_6,\; i\sqrt2,\; i,\; \sqrt2,\; \sqrt3,\; \Phi\}$.
For each of the primes $p$ below and each of the values of $\zeta$ listed, say whether $\pm p$ is in the image of the norm map $N : Z[\zeta] \rightarrow Z$.
- $p = 2$
- $p = 3$
- $p = 2659$
- $p = 4079$
I am new in this subject. I know this problem can be solved by quadratic residue methods in number theory but I cannot figure it out. A detailed solution would be appreciated.
Thank you.
