| Mar 17, 2010 at 5:03 | comment | added | Kim Morrison | I suspect Anton is thinking big here. There's a valid argument that in the broad church of mathematics, there are some researchers, perhaps not yet well represented here, who may run into minor points of algebraic topology while working on something very far removed. They should be welcome, and in fact if we fail to welcome them then we doom mathoverflow to its present parochial specialisations. I'm not sure I agree, but it's a point worth discussing, on meta tea.mathoverflow.net/discussion/291. | |

| Mar 17, 2010 at 0:27 | comment | added | Anton Geraschenko | If it is homework, saying that there's a big theorem that does it probably doesn't finish the homework ... you'd have to run the proof or something. On the other hand, I can imagine somebody with no topology background wanting to know this for some other application, in which case a direct reference is exactly what they'd need to keep making progress. | |
