Colored knot Floer homology: structures and examples

Geometric Topology 2025-09-01 v1

Abstract

Inspired by the SnS^n colored version of Khovanov and Khovanov-Rozansky homology, we define a colored version of knot Floer homology by studying the colimit of a directed system of link Floer homology with infinite full twists. Specifically, our nn-colored knot Floer homology of a knot KK is then defined as the colimit of the link Floer homology of (n,mn)(n, mn)-cables of KK by fixing nn and letting mm goes to infinity. We show that the colimit of the infinite full twists is a module over the colored knot Floer homology of the unknot. In addition, we give an explicit description of colored Heegaard Floer homology for L-space knots, and maps for colored knot Floer homology of crossing changes.
