Structures in HOMFLY-PT homology

Geometric Topology 2024-01-17 v2

Abstract

We study the structure of triply graded Khovanov-Rozansky homology using both the data recently computed by Nakagane and Sano for knots up to 11 crossings, and the sl(2)\mathfrak{sl}(2) action defined by the second author, Hogancamp and Mellit. In particular, we compute the HOMFLY-PT SS-invariant for all knots in the dataset, and compare it to the sl(N)\mathfrak{sl}(N) concordance invariants.
