On the third homotopy group of Orr’s space

- Mathematics
- 2017

K. Orr defined a Milnor-type invariant of links that lies in the third homotopy group of a certain space $K_\omega.$ The problem of non-triviality of this third homotopy group has been open. We show… Expand

On a problem of Bousfield for metabelian groups

- Mathematics
- 2016

Abstract The homological properties of localizations and completions of metabelian groups are studied. It is shown that, for R = Q or R = Z / n and a finitely presented metabelian group G, the… Expand

Link concordance invariants and homotopy theory

- Mathematics

SummaryWe show that each of a sequence of concordance invariants for codimension-two links of spheres inSn+2, defined by Kent Orr, is identically zero forn>1. For classical links (n=1), the same… Expand

On Cotorsion Images of the Baer-Specker Group

- Mathematics
- Irish Mathematical Society Bulletin

A paper in the Bulletin [1] some years ago has discussed in detail the so-called Baer–Specker group P , the full Cartesian product of countably many copies of the integers, Z. Despite its seemingly… Expand

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

- Mathematics
- Compositio Mathematica
- 2018

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… Expand

On homology of Lie algebras over commutative rings

- Mathematics
- 2020

We study five different types of the homology of a Lie algebra over a commutative ring which are naturally isomorphic over fields. We show that they are not isomorphic over commutative rings, even… Expand

The abelianization of inverse limits of groups

- Mathematics
- 2016

The abelianization is a functor from groups to abelian groups, which is left adjoint to the inclusion functor. Being a left adjoint, the abelianization functor commutes with all small colimits. In… Expand

Homological properties of parafree Lie algebras

- Mathematics

Abstract In this paper, an explicit construction of a countable parafree Lie algebra with nonzero second homology is given. It is also shown that the cohomological dimension of the pronilpotent… Expand
