Topological Hochschild homology and the Bass trace conjecture

A. J. Berrick, Lars Hesselholt

We use the methods of topological Hochschild homology to shed new light on the groups satisfying the Bass trace conjecture. We show that the factorization of the Hattori-Stallings…

Periodicity of hermitian K-groups

A. J. Berrick, M. Karoubi, P. A. Østvær

Bott periodicity for the unitary, orthogonal and symplectic groups is fundamental to topological K-theory. Analogous to unitary topological K-theory, for algebraic K-groups with fi…

The acyclic group dichotomy

A. J. Berrick

Two extremal classes of acyclic groups are discussed. For an arbitrary group G, there is always a homomorphism from an acyclic group of cohomological dimension 2 onto the maximum p…

Homotopy idempotents on manifolds and Bass' conjectures

A J Berrick, I Chatterji, G Mislin

The Bass trace conjectures are placed in the setting of homotopy idempotent selfmaps of manifolds. For the strong conjecture, this is achieved via a formulation of Geoghegan. The w…

Hermitian K-theory and 2-regularity for totally real number fields

A. J. Berrick, M. Karoubi, P. A. Østvær

We completely determine the 2-primary torsion subgroups of the hermitian K-groups of rings of 2-integers in totally real 2-regular number fields. The result is almost periodic with…

Homological realization of prescribed abelian groups via -theory

A. J. Berrick, M. Matthey

Using algebraic and topological K-theory together with complex C^*-algebras, we prove that every abelian group may be realized as the centre of a strongly torsion generated group w…
