Pragmatic finiteness properties of locally compact groups

open access: yesmanuscripta mathematica
Abstract We compare finiteness properties of locally compact groups that generalize the properties of being compactly generated and of being compactly presented. Three such families of properties have been proposed: Abels–Tiemeyer’s type $$C_n$$ C

Homological and topological properties of locally indicable groups

open access: yesManuscripta Mathematica, 1983
This is an important paper: The authors show that three classes of groups, which have each been introduced in different contexts and for different reasons, actually coincide. This simplifies the existing theory and sheds new light on work of Adams on the Whitehead problem concerning asphericity in 2-complexes.

Liftings and the property of Baire in locally compact groups [PDF]

open access: yesProceedings of the American Mathematical Society, 1993
R. A. Johnson showed the non-existence of translation-invariant Borel liftings for the Haar measure on \(\mathbb{R}/\mathbb{Z}\). This result has been extended to non-discrete locally compact Abelian groups by M. Talagrand and also in paper of J. Kupka and P. Prikry.

Some local properties defining To-groups and related classes of groups

open access: yesPublicacions Matemàtiques, 2016
We call G a HallX -group if there exists a normal nilpotent subgroup N of G for which G/N0 is an X-group. We call G a T0-group provided G/Φ(G) is a T -group, that is, one in which normality is a transitive relation. We present several new local classes of groups which locally define HallX -groups and T0-groups where X ∈ {T , PT , PST }; the classes PT ...
