Is PA consistent? do we know it?
@DavidRoberts - Sorry, I didn't express myself well. I shouldn't have said "explicit". I edited. Thanks! |

Trace of the identity map in a projective module
PS. I think $M=M/(1-e_i)M$ should be $M_i=M/(1-e_i)M$. |

Dear Todd: This is just to tell you that I posted a minor complement to your great answer as a community wiki answer. |

dim Hom(V,W) =?
To me, it was invaluable! (Also I now realize - thanks to you, Todd and François - how easy it was to answer my question using the Erdős-Kaplansky Theorem, and how silly my approach was...) |

Dimension of infinite product of vector spaces
Dear François: Here is a tiny bit of nitpicking. I find your question very nice, but I think it would be more correct to write in your blockquote "a family of nonzero vector spaces" instead of "a family of vector spaces". |

Dear Fernando: Thanks for you answer. I especially enjoyed the answer mathoverflow.net/a/49572/461 of Todd Trimble's to the question you linked to! |
