ON THE JONES POLYNOMIAL OF QUASI-ALTERNATING LINKS, II

We extend a result of Thistlethwaite [17, Theorem 1(iv)] on the structure of the Jones polynomial of alternating links to the wider class of quasi-alternating links. In particular, we prove that the Jones polynomial of any prime quasi-alternating link that is not a (2, n)-torus link has no gap. As an application, we show that the differential grading of the Khovanov homology of any prime quasi-alternating link that is not a (2, n)-torus link has no gap. Also, we show that the determinant is an upper bound for the breadth of the Jones polynomial for any quasi-alternating link. Finally, we prove that the Jones polynomial of any non-prime quasi-alternating link L has more than one gap if and only if L is a connected sum of Hopf links.
