Then the boundary maps δn : H 1(G,π/[π]n)→ H(G, [π]n/[π]n+1) are Massey products. When the action is more general, we partially compute these boundary maps. Via obstructions of Jordan Ellenberg, this implies that π1 sections of ...

Weband X= X/G˜ . Also Hn(X) and Hn(X) depend only on π1(X). If G= π1(X) we may thus deﬁne Hn(G,Z) = Hn(X) and Hn(G,Z) = Hn(X) and because Xis determined up to homotopy equivalence the deﬁnition does not depend on X. As an example we could take X to be dloops joined together at a point. Then π1(X) = Fd is free on dgenerators and πn(X WebFor example, we have H0(π) = Z for all π (so H0 is a boring invariant of π), and H1(π) = πab:= π/[π,π], the abelianization of π.
