We prove that for a subring R ⊆ Q and a free group F of rank at least 2 the length of the Bousfield’s HR-localization tower for F is at least ω + ω. The key ingredient of the proof is the theory of polynomial functors over Q.

On Cubic Functors

Abstract We prove that the description of cubic functors is a wild problem in the sense of the representation theory. On the contrary, we describe several special classes of such functors

On discrete homology of a free pro- $p$ -group

For a prime $p$ , let $\hat{F}_{p}$ be a finitely generated free pro- $p$ -group of rank at least $2$ . We show that the second discrete homology group $H_{2}(\hat{F}_{p},\mathbb{Z}/p)$ is an

On lengths of HZ-localization towers

In this paper, the $H\mathbb Z$-length of different groups is studied. By definition, this is the length of $H\mathbb Z$-localization tower or the length of transfinite lower central series of

Relative Schur multipliers and universal extensions of group homomorphisms

In this note, starting with any group homomorphism $f\colon\Gamma\to G$, which is surjective upon abelianization, we construct a universal central extension $u\colon U\twoheadrightarrow G,$ UNDER
