Gauss notation (also known as a Gauss code or Gauss words [1]) is a notation for mathematical knots. [2] [3] It is created by enumerating and classifying the crossings of an embedding of the knot in a plane. [2] [4] [5] It is named after the German mathematician Carl Friedrich Gauss (1777–1855). Gauss code represents a knot with a sequence of ...
The Tom fool's knot, also known as the conjurer's knot, bow knot and Greek fool's knot, is a type of knot sometimes considered a handcuff knot, though usually considered somewhat inferior to it. [1] : 208 It is a good knot with which to commence a slightly fancy sheepshank. [1] : 210 It is also used as a trick knot due to the speed with which ...
The signature of a knot is a topological invariant in knot theory. It may be computed from the Seifert surface . Given a knot K in the 3-sphere, it has a Seifert surface S whose boundary is K. The Seifert form of S is the pairing given by taking the linking number where and indicate the translates of a and b respectively in the positive and ...
