Abstract
A knot is an embedding of a circle into 3dimensional euclidean space,
e : S1
R3
, and two knots are considered to be equivalent if the embeddings
are isotropic.
The problem of classifying knots has a history that goes back more than one
century. Many invariants of knots have been discovered, from the Alexander
polynomial in the 1920's to the Jones and HOMFLY polynomials in the 1980's.
A more global viewpoint on this classification emerged with the work of
Vassiliev who studied the space of all embeddings e : S1
R3
