A comparison of two quantum distances
Jens Kaad, David Kyed
We show that Rieffel's quantum Gromov-Hausdorff distance between two compact quantum metric spaces is not equivalent to the ordinary Gromov-Hausdorff distance applied to the associ…
Factorization of Dirac operators on almost-regular fibrations of spin manifolds
Jens Kaad, Walter D. van Suijlekom
We establish the factorization of the Dirac operator on an almost-regular fibration of spin manifolds in unbounded KK-theory. As a first intermediate result we establish that a…
On a spectral flow formula for the homological index
Alan Carey, Harald Grosse, Jens Kaad
Consider a selfadjoint unbounded operator D on a Hilbert space H and a one parameter norm continuous family of selfadjoint bounded operators {A(t)} parametrized by the real line. T…
Anomalies of Dirac type operators on Euclidean space
Alan Carey, Harald Grosse, Jens Kaad
We develop by example a type of index theory for non-Fredholm operators. A general framework using cyclic homology for this notion of index was introduced in a separate article [Ca…
