The Relation To Link(knot) Polynomials
At International Congress of Mathematicians in 2006 Mikhail Khovanov provided the following explanation for for the relation to knot polynomials from the view point of Khovanov homology. The skein relation for three links and is described as
Substituting leads to a link polynomial invariant, normalized so that for
and . For the polynomial can be interpreted via the representation theory of quantum group and via that of the quantum Lie superalgebra .
- The Alexander polynomial is the Euler characteristic of a bigraded knot homology theory.
- is trivial.
- The Jones polynomial is is the Euler characteristic of a bigraded link homology theory.
- The entire HOMFLY-PT polynomial is the Euler characteristic of a triply-graded link homology theory.

Famous quotes containing the word relation:
“[Man’s] life consists in a relation with all things: stone, earth, trees, flowers, water, insects, fishes, birds, creatures, sun, rainbow, children, women, other men. But his greatest and final relation is with the sun.”
