WebLet G be a group given by a free presentation G = F/N, and N' the commutator subgroup of N. The quotient F/N' is called a free abelianized extension of G. We study the homology of F/N' with trivial coefficients. In particular, for torsion-free G our main result yields a complete description of the odd torsion in the integral homology of F/N' in terms of the mod p … WebThe upshot of all this is that the stable homology of symmetric groups is the same as H 0 (1S;Z) and so related to stable homotopy of spheres (the 0 subscript in 0 denotes taking a single connected component). 1.3.3 Serre’stheoremandvariations By homological stability for symmetric groups, we have an isomorphism H 0 (B n;Z) ˘=H (1S) for n 1 2.
