Lee filtration structure of torus links

Geometric Topology 2024-12-25 v3 Quantum Algebra

Abstract

We determine the quantum filtration structure of the Lee homology of all torus links. In particular, this determines the ss-invariant of a torus link equipped with any orientation. In the special case T(n,n)T(n,n), our result confirms a conjecture of Pardon, as well as a conjecture of Manolescu-Marengon-Sarkar-Willis which establishes an adjunction-type inequality of the ss-invariant for cobordisms in kCP2k\overline{\mathbb{CP}^2}. We also give a few applications of this adjunction inequality.
