The space of Dirac operators for the Connes-Chamseddine spectral action for the standard model of particle physics coupled to gravity is studied. The model is extended by including right-handed neutrino states, and the S-reality axiom is not assumed. The possibility of allowing more general fluctuations than the inner fluctuations of the vacuum is proposed.… (More)
New data for the viscosity of argon at high temperatures indicate that the accepted data are substantially too low at temperatures above 600 degrees K.
As a natural and canonical extension of Kumjian’s Fell bundles over groupoids , we give a definition for a double Fell bundle (a double category) over a double groupoid. We show that finite dimensional double category Fell line bundles tensored with their dual satisfy the finite real spectral triples axioms except for orientability. This means that… (More)
