Axiom 1: If Kis the trivial knot, then r K(z) = 1. The Jones polynomial is an assignment of Laurent polynomials VL(t) in the vari-able p t to oriented links L subject to the following three axioms. Many people have pondered why this is so, and what a proper generalization regular diagram for K.

The colored Jones polynomial of a knot K in 3-space is a q-holonomic sequence of Laurent polynomials of nat-ural origin in quantum topology [Garoufalidis and Lˆe Thang 05]. It is not known if there is a nontrivial knot with Jones polynomial 1. of Laurent polynomials in E and Q that satisfy the commutation relation EQ = qQE.

Exercise 5.1    Let us calculate trivial knot. Many people have pondered why is this so, and what is a proper generalization of the Jones polynomial for knots in other closed 3-manifolds.

Exercise 5.1    Let us calculate trivial knot. Many people have pondered why is this so, and what is a proper generalization of the Jones polynomial for knots in other closed 3-manifolds.
