Further Study of Kanenobu Knots

Abstract

We determine the rational Khovanov bigraded homology groups of all Kanenobu knots. Also, we determine the crossing number for all Kanenobu knots $K(p,q)$ with $pq > 0$ or $|pq|\leq \max \{|p|, |q|\}$. In the case where $pq < 0$ and $|pq| > \max \{|p|, |q|\}$, we conjecture that the crossing number is $|p| + |q| + 8$.
