The Connes-higson Construction Is an Isomorphism
نویسنده
چکیده
Let A and B be separable C-algebras, B stable. We show that the Connes-Higson construction gives rise to an isomorphism between the group of unitary equivalence classes of extensions of SA by B, modulo the extensions which are asymptotically split, and the homotopy classes of asymptotic homomorphisms from SA to B.

Inheritance of Isomorphism Conjectures under colimits
We investigate when Isomorphism Conjectures, such as the ones due to Baum-Connes, Bost and Farrell-Jones, are stable under colimits of groups over directed sets (with not necessarily injective structure maps). We show in particular that both the K-theoretic Farrell-Jones Conjecture and the Bost Conjecture with coefficients hold for those groups for which Higson, Lafforgue and Skandalis have dis...
متن کاملShape Theory and Asymptotic Morphisms for C*-algebras
In this paper we relate two topological invariants of a separable C*-algebras. The first is the shape invariant first studied by Effros and Kaminker [EK] and then developed further by Blackadar [B]. The second invariant is the isomorphism class of a C*-algebra in the asymptotic homotopy category A introduced by Connes and Higson [CH]. We prove that two separable C*-algebras are shape equivalent...

متن کاملA Thom Isomorphism for Infinite Rank Euclidean Bundles
An equivariant Thom isomorphism theorem in operator K-theory is formulated and proven for infinite rank Euclidean vector bundles over finite dimensional Riemannian manifolds. The main ingredient in the argument is the construction of a non-commutative C-algebra associated to a bundle E → M , equipped with a compatible connection ∇, which plays the role of the algebra of functions on the infinit...
متن کاملSome Notes on Property A
Introduction The coarse Baum-Connes conjecture states that a certain coarse assembly map µ : KX * (X) → K * (C * (X)) is an isomorphism (see for example [Roe96] or the piece by N. Higson and J. Roe in [FRR95]). It has many important consequences including one of the main motivations for this piece: a descent technique connects it to injectivity of the ('ordinary') Baum-Connes assembly map µ : K...
