Notes for AKT-090915/0:03:24

Review and additions to last class, corrections:

1. Jones polynomial is usually normalized by diving the '<>' of an unknot (i.e. divide by an additional factor of $d$).
2. We can prove all knot $K$ has $J(K)$ being a polynomial of $A^{4}$, hence we substitute $A=q^{1/4}$.
