A Property of Finite Rings @Tom: I am afraid the argument is not right. How do you conclude that the sum of all $a(x)$'s and the sum of all $b(x)$'s are equal ?! |

on the Axiom of Choice and the Spectrum of Rings @Martin: I am interested in algebraic equivalents of AC. So as an old habit whenever I see an application of AC I ask myself is that necessary to use AC ? In this particular problem, I don't know the answer. |

on the Axiom of Choice and the Spectrum of Rings @François: By zero-dimensional I mean every prime ideal is maximal. |

The set of orders of elements in a group @Todd: Yes. Note that this does not affect the generality of the problem. since if $B = A\cup\lbrace\infty\rbrace$ then $G\oplus\mathbb{Z}$ whould be the answer. |

Number of Maximal Left Ideals @Martin: I'm afraid there is no such Boolean algebra. Since maximal ideals are in two-sided correspondence with ultrafilters and if $R$ is a superatomic Boolean algebra then $|Ult(R)| = |R|$ and if $R$ is not superatomic then $|Ult(R)| > 2^{\aleph_0}$. So it seems that there is no uncountable Boolean algebra with only a countable number of ultrafilters. |

Number of Maximal Left Ideals @Martin: Right, thanks. Lets continue: How about reduced rings ? Do you have any reduced example ? |

Is it necessary to use AC to solve this problem ? @Clinton: Very Nice. $A$ is the transfers of the Cantor ternary set. |
