SL(2,C) Gravity with Complex Vierbein and Its Noncommutative Extension
Ali H. Chamseddine
We show that it is possible to formulate gravity with a complex vierbein based on SL(2,C) gauge invariance. The proposed action is a four-form where the metric is not introduced bu…

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…

Spontaneous Symmetry Breaking for Massive Spin-2 Interacting with Gravity
Ali H. Chamseddine
An action for a massless graviton interacting with a massive tensor field is proposed. The model is based on coupling the metric tensor to an SP(4) gauge theory spontaneously broke…
