Talk:Alternating knot

From Wikipedia, the free encyclopedia

You have new messages (last change).

Stuff that should be added to this article:

  • Who invented the concept? Who first proved something non-trivial about alternation? Who first proved a knot to be non-alternating?
  • How does one prove a knot is non-alternating? I suspect the polynomial invariants identify non-alternating knots, but I don't know.
  • What's the simplest non-alternating link? Pictures?
  • Are there any theorems that have "alternating" as a hypothesis?

Some of the questions are answered by now. Some stuff to be added: explanation of how to show a knot is non-alternating (Alexander polynomial can be used). Alternating knots go back to Tait, and even before him to celtic knots and artwork. --Chan-Ho (Talk) 13:42, 9 January 2006 (UTC)
