WebLet G be a profinite group acting continuously on π. First suppose that the action is given by a character. 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 ... photo of isaac cline

Web• When the set S consists of a single element S = {h} then the normalizer of {h} in G is also called the centralizer of h in G C G(h) = C(h) = {g ∈ G : ghg−1 = h}, i.e. the set of elements of G that commute with h.

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
