Khovanov homology and exotic $4$ -manifolds

Qiuyu Ren, Michael Willis

We show that the Khovanov-Rozansky $gl_{2}$ skein lasagna module distinguishes the exotic pair of knot traces $X_{- 1} (- 5_{2})$ and $X_{- 1} (P (3, - 3, - 8))$ , an example first dis…

Khovanov skein lasagna modules with $1$ -dimensional inputs

Qiuyu Ren, Ian Sullivan, Paul Wedrich +2

We construct a variant of Khovanov skein lasagna modules, which takes the Khovanov homology in connected sums of $S^{1} \times S^{2}$ defined by Rozansky and Willis as the input link ho…
