Supergravity vacua and lorentzian Lie groups
Ali Chamseddine, José Figueroa-O'Farrill, Wafic Sabra
We classify maximally supersymmetric backgrounds (vacua) of chiral (1,0) and (2,0) supergravities in six dimensions and, by reduction, also those of the minimal N=2 supergravity in…

Chiral Anomalies in the Spectral Action
Ali H. Chamseddine
The definition of the spectral action involves the trace operator over states in the physical Hilbert space. We show that in the presence of chiral fermions there are consistency c…

Particle Physics Models, Grand Unification, and Gravity in Non-Commutative Geometry
A. H. Chamseddine, J. Fröhlich
We review the construction of particle physics models in the framework of non-commutative geometry. We first give simple examples, and then progress to outline the Connes-Lott cons…
