| Mar 26, 2010 at 17:06 | comment | added | Franz Lemmermeyer | This seems to be essentially the same as mathoverflow.net/questions/14689/… | |

| Mar 26, 2010 at 15:45 | comment | added | Kevin Buzzard | No (assuming by the "Galois group of P" you mean the Galois group of its splitting field, and assuming by "correlation" you mean "can I work out the Galois group of P given only the G_i"), because you need to know how the splitting fields of the Q_i interact. Consider for example the cases P=(x^2-2)(x^2-8) and P=(x^2-2)(x^2-3). | |
