### Skein relations for Milnor's $\mu$-invariants

Michael Polyak

#### Abstract

The theory of link-homotopy, introduced by Milnor, is an important part of the knot theory, with Milnor’s $μ̄$–invariants being the basic set of link-homotopy invariants. Skein relations for knot and link invariants played a crucial role in the recent developments of knot theory. However, while skein relations for Alexander and Jones invariants are known for quite a while, a similar treatment of Milnor’s $μ̄$–invariants was missing. We fill this gap by deducing simple skein relations for link-homotopy $μ$–invariants of string links.
