Summary:
|
Let $p$ and $q$ be two different prime integers such that $p\equiv q\equiv 3\pmod 8$ with $(p/q)=1$, and $l$ a positive odd square-free integer relatively prime to $p$ and $q$. In this paper we investigate the unit groups of number fields $\mathbb L=\mathbb {Q}(\sqrt {2}, \sqrt {p}, \sqrt {q}, \sqrt {-l})$. (English) |
