I wanted to understand Milnor’s paper on Link Groups, so I basically rewrote the main bits in to Milnor mu-bar invariants. (I don’t understand the difference between $\mu$-invariants and $\bar{\mu}$-invariants, but I was only working on the original paper so presumably haven’t gotten that far yet.)

I even put a TOC in so Urs will be happy!

Great! That does make me happy ;-)

And even happier that I nevertheless found some formatting to improve: added the link to John Milnor

Ah! I didn’t know that he had a page here. (Mind you, I guess I should have just wiki-linked his name on the off-chance.)

I’m hoping that Tim Porter will stop by and enlighten me as to the difference between $\mu$ and $\bar{\mu}$. Also, the page at present is about both the link group and the $\mu$-invariants. My intention (though I forgot) was to make that page redirect from “link group” as well. Does anyone more knowledgeable than me see an immediate reason to split this in to two pages? (Of course, it can always be split later.)
