Abstract

Using a definition of Euler characteristic for fractionally-graded complexes based on roots of unity, we show that the Euler characteristics of Dowlin's "sl(n)\mathfrak{sl}(n)-like" Heegaard Floer knot invariants HFKnHFK_n recover both Alexander polynomial evaluations and sl(n)\mathfrak{sl}(n) polynomial evaluations at certain roots of unity for links in S3S^3. We show that the equality of these evaluations can be viewed as the decategorified content of the conjectured spectral sequences relating sl(n)\mathfrak{sl}(n) homology and HFKnHFK_n.
