Takefumi Nosaka (Tokyo institute of Technology)
Milnor invariants via unipotent Magnus embeddings (JAPANESE)
[ Abstract ]
We reconfigured the Milnor invariant, in terms of central group extensions and unipotent Magnus embeddings, and develop a diagrammatic computation of the invariant. In this talk, we explain the reconfiguration and the computation with mentioning some examples. I also introduce some properties of the unipotent embeddings. This is a joint work with Hisatoshi Kodani.
