III --> Ш

| Aug 2, 2011 at 5:42 | comment | added | Chandan Singh Dalawat | Would be nice to insert the Cyrillic Ш instead of III. | |

divides --> does not divide

| Aug 1, 2011 at 18:14 | comment | added | Franz Lemmermeyer | My definition of locally principal does not mean that the ideal is principal in the localization, which, as you're saying, is always the case. Essentially locally principal means that there is no "genus obstruction" to being principal. In the quadratic case of a field with discriminant $4m$, an ideal with norm $a$ is locally principal if $x^2 - my^2 = a$ has local solutions everywhere. | |
