Homology of the Infinite Symmetric Group
The Annals of Mathematics, 1961H*(S(co); Z.,) with coefficients in the integers mod p (p :prime). It is proved that the height of any non-zero element is co if p = 2, and is either co or < p if p is odd. If p = 2 this fact and the result in [11, ? 6] enable us to determine the structure of the cohomology algebra H*(S(oo); Z2) by using Borel's theorem on the structure of Hopf ...

On the subsheaves of the sheaf of the homology groups
1997Let \(X\) be a connected complex manifold. For each \(x\in X\), let \(H_x= \pi_1 (X,x)\) and let \({\mathcal H}_x =H_x/N_x\) where \(N_x\) is the commutator subgroup of \(H_x\). The authors obtain a sheaf \(({\mathcal H}, \pi)\) over \(X\). They classify the subsheaves of \({\mathcal H}\).
