L-Space Knots in sln-like Knot Floer Homology
Abstract
It has been of particular interest in recent years to relate categorifications of quantum knot invariants like the Jones polynomial to Floer-theoretic invariants like knot Floer homology using spectral sequences. In pursuit of Rasmussen's conjecture, Dowlin constructed a family of invariants with properties like those of Khovanov and Rozansky's sln-homology theories. In this paper, we explore these invariants for L-space knots and thin knots. In particular, for n≥ 2 the invariants of thin knots can be computed from a change of coefficients from the minus flavor of knot Floer homology, and the same holds for an L-space knot exactly when an explicit condition relating n to its Alexander polynomial is satisfied.
