The KO-valued spectral flow for skew-adjoint Fredholm operators

Chris Bourne, Alan L. Carey, Matthias Lesch +1

In this article we give a comprehensive treatment of a `Clifford module flow' along paths in the skew-adjoint Fredholm operators on a real Hilbert space that takes values in KO${}_…

The non-unital version of Connes' theorem on the Hochschild class of the Chern character

Alan L. Carey, A. Rennie

We offer a short proof of Connes' Hochschild class of the Chern character formula for non-unital semifinite spectral triples. The proof is simple due to its reliance on the authors…

Topological invariance of the homological index

Alan Carey, Jens Kaad

R. W. Carey and J. Pincus in [CaPi86] proposed and index theory for non-Fredholm bounded operators T on a separable Hilbert space H such that TT* - T*T is in the trace class. We sh…

Higher spectral flow and an entire bivariant JLO cocycle

Moulay-Tahar Benameur, Alan L. Carey

Given a smooth fibration of closed manifolds and a family of generalised Dirac operators along the fibers, we define an associated bivariant JLO cocycle. We then prove that, for an…

Riemann-Roch and index formulae in twisted K-theory

Alan L. Carey, Bai-Ling Wang

In this paper, we establish the Riemann-Roch theorem in twisted K-theory extending our earlier results. As an application, we prove a twisted index formula and show that D-brane ch…

Twisted cyclic theory and an index theory for the gauge invariant KMS state on Cuntz algebras

A. L. Carey, J. Phillips, A. Rennie

This paper presents, by example, an index theory appropriate to algebras without trace. Whilst we work exclusively with the Cuntz algebras the exposition is designed to indicate ho…

A noncommutative Atiyah-Patodi-Singer index theorem in KK-theory

A. L. Carey, J. Phillips, A. Rennie

We investigate an extension of ideas of Atiyah-Patodi-Singer (APS) to a noncommutative geometry setting framed in terms of Kasparov modules. We use a mapping cone construction to r…

Thom isomorphism and Push-forward map in twisted K-theory

Alan L. Carey, Bai-Ling Wang

We establish the Thom isomorphism in twisted K-theory for any real vector bundle and develop the push-forward map in twisted K-theory for any differentiable proper map …

Spectral flow in Fredholm modules, eta invariants and the JLO cocycle

Alan L. Carey, John Phillips

We give a comprehensive account of an analytic approach to spectral flow along paths of self-adjoint Breuer-Fredholm operators in a type or von Neumann alg…
