Lee filtration structure of torus links
arXiv:2305.16089 · doi:10.2140/gt.2024.28.3935
Abstract
We determine the quantum filtration structure of the Lee homology of all torus links. In particular, this determines the -invariant of a torus link equipped with any orientation. In the special case , 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 -invariant for cobordisms in . We also give a few applications of this adjunction inequality.
