Triplets spectraux pour les variétés à singularité conique isolée

Triplets spectraux pour les variétés à singularité conique isolée

We use elliptic operators of Fuchs type on an even dimensional pseudomanifold with an isolated singularity to construct spectral triples. This class of operators includes Dirac operators with coefficients in flat bundles in the radial direction and, under some hypothesis, these operators generate the even K-homology group tensorised by ℂ …
