Notes

  1. This is called ambient isotopy in the literature.

  2. The equivalence relation here is ambient isotopy.

  3. The precise notion of equivalence here is again ambient isotopy.

  4. See also a framed knots movie representation available at http://www.youtube.com/watch?v=KxEBhD0C2Pw.

  5. A linking number movie can be viewed at https://www.youtube.com/watch?v=_qOl_5KcANE.

  6. A Seifert surface movie can be viewed at http://www.youtube.com/watch?v=px3Gq_gvvac.

  7. This is a result of Smale’s theorem, which states that every orientation-preserving diffeomorphism of the 2-sphere is smoothly isotopic to the identity map.
