Milnor invariants of length $2k+2$ for links with vanishing Milnor invariants of length $\le k$

Yuka Kotorii, Akira Yasuhara

J.-B. Meilhan and the second author showed that any Milnor $\bar{\mu }$-invariant of length between 3 and $2k+1$ can be represented as a combination of HOMFLYPT polynomial of knots obta…
