| Jun 1, 2012 at 18:32 | comment | added | Greg Friedman | @Mark. Thanks - that explains why it looked like it was almost working. @Ralph - the boundedness is usually needed because the homotopy operators are (in the most hands-on proofs) constructed inductively and you need some place to start the induction. Have a look at the proof of the theorem in Munkres that I cited. Conceivably this is a simple enough case that there's some way around this, but I'll have to think about it/hunt around. | |

| Jun 1, 2012 at 5:48 | comment | added | Mark Grant | @Greg Friedman: The align environment works - the only trick is to replace \\ with \newline. Probably eqnarray works too (but I didn't try that yet). | |
