Cyclotomic Integer with a Given Norm? |
Dear Sirs (and Mesdames): Can someone tell me if there is a ready and easy way to decide with PARI whether there exists an integer $a$ in a cyclotomic field $Q(\zeta_n)$ with a given norm $p$, where $p$ is a prime number? Thanks for any tips or pointers to knowledge. Sincerely, Bo-Yin Yang
