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…

Unbounded symmetric operators in -homology and the Baum-Connes Conjecture

Hela Bettaieb, Michel Matthey, Alain Valette

Using the unbounded picture of analytical K-homology, we associate a well-defined K-homology class to an unbounded symmetric operator satisfying certain mild technical conditions.…

Homotopy invariance of higher signatures and 3-manifold groups

Michel Matthey, Hervé Oyono-Oyono, Wolfgang Pitsch

For closed oriented manifolds, we establish oriented homotopy invariance of higher signatures that come from the fundamental group of a large class of orientable 3-manifolds, inclu…
