Abstract

We classify all links whose Khovanov homology have ranks no greater than $8$, and all three-component links whose Khovanov homology have ranks no greater than $12$, where the coefficient ring is $\mathbb{Z}/2$. The classification is based on the previous results of Kronheimer–Mrowka [8], Batson–Seed [3], Baldwin–Sivek [1], and the authors [19].
