Talk:Kolmogorov–Arnold representation theorem

Recent Improvements
I posted a public domain constructive proof of this theorem by Braun and Griebel. Most of the original material is in Russian, or paywalled translations, so it was not easy to find an English language source for this. The Braun and Griebel source seems to sum up the modern understanding of this theorem (along with an accurate constructive proof), which is important since so much has changed over the last 60 years since the theorem was originally published. Modern proofs are much better and more specific than the original formulations. This should make it much easier for those who wish to learn more to find some decent source material. I also added the more specific statement of the theorem.

2nd Example
The 2nd example seems to be wrong. It has one too many nestings. 2A02:8109:AD3F:FCD4:45A7:CF44:983E:69D (talk) 20:32, 31 May 2016 (UTC)
