Random walk invariants of string links from R–matrices

Thomas Kerler and Yilong Wang

Algebraic & Geometric Topology 16 (2016) 569–596
Abstract

We show that the exterior powers of the matrix valued random walk invariant of string links, introduced by Lin, Tian, and Wang, are isomorphic to the graded components of the tangle functor associated to the Alexander polynomial by Ohtsuki divided by the zero graded invariant of the functor. Several resulting properties of these representations of the string link monoids are discussed.
