Is there a way to appreciate your work in what I will be writing up later? The context is an open loop (quantum or classical) control problem for which I required the existence of these numbers as a step in a recipe. I could acknowledge mathoverflow.net but that won't be sufficient in this case, I think. | |

| Nov 23, 2009 at 20:24 | comment | added | Reid Barton | To see whether I understand this: This solution produces xs and ys inside some fixed interval, as in the original problem? And it's essentially that the power sums we want to be equal start at Ω(n) and not at 1, as shown by David's argument? | |

replace "implicit" by "inverse" as more appropriate
