“…Ordinary and higher order linking numbers provide, among others, a quite useful tool for the investigation of Brunnian phenomena in knot theory: recall that a link is almost trivial or Brunnian if upon removing any component therefrom one gets a trivial link (see figure 5.8). They can be defined recursively in terms of Massey products, or equivalently, Milnor invariants, by the celebrated Turaev-Porter theorem (see [FF83,PS02,Spe06,HT12]). We are going to review, briefly and quite concretely, the basic steps of the Massey procedure, read differential geometrically as in [PS02, Spe06, HT12], presenting at the same time our novel multisymplectic interpretation thereof.…”
