Books you would like to read (if somebody would just write them…)
Well, you are one of the lucky ones! There are now two volumes recently published by de SMF in the Documents Mathématiques series. |

Is every finite group a group of “symmetries”?
@Andrew: I am also sure I have seen a proof that every finite group is a group of automorphisms of a Riemann surface, actually in the context of the Inverse Galois Problem, but the only reference for something quite close that I could find now is: L. Greenberg, Conformal transformations of Riemann surfaces. Amer. J. Math. 82 1960 749–760. |

Examples of theorems misapplied to non-mathematical contexts
Perhaps it was my being ignorant of algebraic topology as a kid, but splitting my sandwich with my brother did not seem to be fair! |

Never appeared forthcoming papers
I recalled Robert Thomason citing the various preprints of his paper "Algebraic K-theory and etale cohomology" as "to disappear" We are all glad that the paper finally appeared in Ann. Sci. Ecole Norm. Sup. (1985). |

Mittag-Leffler condition: what's the origin of its name?
Thanks Yemon. I followed your suggestion and took a look at Runde's (Appendix A) and the "abstract" Bourbaki's M-L version for a sequence of complete metric spaces and continuous funcions $f_n:X_n\rightarrow X_{n-1}$ with dense image. It looks that this can be further abstracted to the "algebraic" M-L. I'll do the details later on to see if this is the case. By the way, Runde quotes Bourbaki's "General Topology" volume. I don't have access to that one right now but I'll check it tomorrow. Thanks again. |
