| Jul 9, 2012 at 5:59 | comment | added | David Corwin | I just want to mention that this question came up in a totally different context! It was about proving the (weak) Mordell-Weil Theorem for elliptic curves over number fields. There is a proof that works only when $K$ has class number $1$. Of course, if we can embed $K$ in a field with class number $1$, then the theorem follows a fortiori in $K$ because of its truth in the larger field. | |
