11 Checks For a = q 2 and t = 1, the above formulae reduce to the colored Jones polynomials For t = 1, they reduce to the colored HOMFLY polynomials. We checked they agree with the colored HOMFLY polynomials computed by SU(N) Chern-Simons theory up to 10 crossings. The colored HOMFLY polynomials can be reformulated into the Ooguri-Vafa polynomials. We checked that the Ooguri-Vafa polynomials have interger coefficients up to specific factors.
