Notes for AKT-090915/0:03:24

Review and additions to last class, corrections:

1. 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 $d$).
2. 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 $q$.
