Extreme point compact convex set.
The idea was to try and get a proof that a convex set has an extreme point without using any of the "transcendental" lemmata - like Axiom of Choice, Zorn's Lemma, Hahn-Banach, etc. In complete generality, it appears that Krein Milman requires at least one of these big guns. On the other hand, we also found that my simple proof works in most of the spaces I care about, and the other proof (construct any strictly convex function in the space) is even simpler and can work in all the spaces I care about; I used that approach in my notes. |

@Stankewicz: That's a good point. |

Oneupsmanship and Publishing Etiquette
My suggestion was to "SEE IF the other author WANTS to be a co-author". It seems people are wrongly assuming that this could only mean "see if you can subscribe the other author to the existing paper". These are quite different things, and I don't think people have thought that through. Establishing a collaboration could have many different editorial results; in particular, one possibility is that the other author might suggest useful ways to improve the paper but not subscribe. Or other further significant results might be forthcoming from that author. That's why SEE IF and WANTS. |

I didn't know that community wiki had that property. Having my reputation drained on this wouldn't be unreasonable though. The acadmic thinking about publication is a lot more cutthroat than mine. But in industry, I put a premium on evidence of good collaboration skills when hiring mathematicians. In fact, the one thing I would say about the top tier tenured faculty I did hire at one point is that they did not collaborate anywhere near as well as people we hired as postdocs. |

I see by my draining reputation that this one is not too popular. But consider the original questioner has pointed out that his result is not completely new - he is simply patching up the lack of generality of previous work. Drawing lines in the sand about credit for that seems a bit of a stretch. |

What are some famous rejections of correct mathematics?
I think the easiest way to fit that into the limited characters allowed here is to point at the wikipedia page for Alfven waves: en.wikipedia.org/wiki/Alfv%C3%A9n_wave This was the rule, not the exception for Alfven. Even after his Nobel he didn't get much respect, (except from guys like Fermi and Chandrasekhar - you could do worse). It's also worth looking at his wikipedia page: en.wikipedia.org/wiki/Hannes_Alfv%C3%A9n |

Using Wavelet Transforms to Approximate Matrices
It's OK to show us a bit of the inverse. |

Extreme point compact convex set.
This question was for a mathematical preliminary section in some lecture notes I am writing. If I use it, how should I cite the example you gave? |

MicroArray, tesing if a sample is the same with high variance data.
Mathoverflow insists on changing the display of numbers in my sections - I actually have typed in 1. 2. and 3. I do not know why they display as 1. 1. and 1. in the final. |
