Review and additions to last class, corrections:

The Jones polynomial is usually normalized by diving by $\left\langle \bigcirc \right\rangle$ , the bracket of the unknot (i.e. dividing by an additional factor of $d$ ).
We can prove that for any knot $K$ , $J(K)$ is a polynomial of $A^{4}$ . Hence, we can substitute $A=q^{1/4}$ to get a Laurent polynomial in $q$ .
