TLDR
In this article, a 3+summable spectral triple Open Image in new window over the quantum group SUq(2) which is equivariant with respect to a left and a right action was constructed.Abstract:
We construct a 3+-summable spectral triple Open image in new window over the quantum group SUq(2) which is equivariant with respect to a left and a right action of Open image in new window The geometry is isospectral to the classical case since the spectrum of the operator D is the same as that of the usual Dirac operator on the 3-dimensional round sphere. The presence of an equivariant real structure J demands a modification in the axiomatic framework of spectral geometry, whereby the commutant and first-order properties need be satisfied only modulo infinitesimals of arbitrary high order.read more

The Dwelling of the Spectral Action
TL;DR: The natural habitat of the spectral action is Connes' noncommutative geometry as mentioned in this paper, and it is indispensable to lay out its rudiments encoded in the notion of a spectral triple.
Twisted K-Theory and Gerbes from Hamiltonian Quantization
TL;DR: In this article, the authors review recent progress in the application of the methods of Hamiltonian quantization to construct twisted K-theory elements and gerbes and present a new line of research to apply the ideas of low dimensional quantum field theories on a product manifold T × M to give explicit constructions of gerbes.

Noncommutative geometry and reality
TL;DR: The notion of real structure in spectral geometry was introduced in this paper, motivated by Atiyah's KR•theory and by Tomita's involution J. It allows us to remove two unpleasant features of the Connes-Lott description of the standard model, namely, the use of bivector potentials and the asymmetry in the Poincare duality and in the unimodularity condition.
