least prime in a arithmetic progression
In fact, the Bach-Sorenson bound has been improved. See math.uiuc.edu/~xiannan/QuaResL1ver2.pdf |

When is the tensor product of two fields a field?
Dear Georges, I was actually suggesting to use Prop 107 of Pete's notes, if linear disjointness is considered well-understood. |

Is linear disjointness considered a well-understood condition? If so, it suffices to check that images of $K$ and $L$ in $E$ are linearly disjoint for any extension $K,L \to E$. For this we can check dimensions as Ralph said, at least for finite extensions. |

Locally constant functions with compact support = smooth ?
So if differentiable means that $f'(x)$ exists, does it imply that infinitely differentiable = locally constant? |
