Classification of string links up to $2n$-moves and link-homotopy

Geometric Topology 2019-02-19 v1

Abstract

Two string links are equivalent up to 2n2n-moves and link-homotopy if and only if their all Milnor link-homotopy invariants are congruent modulo nn. Moreover, the set of the equivalence classes forms a finite group generated by elements of order nn. The classification induces that if two string links are equivalent up to 2n2n-moves for every n>0n>0, then they are link-homotopic.
