Scale Invariance in the Spectral Action
Ali H. Chamseddine, Alain Connes
The arbitrary mass scale in the spectral action for the Dirac operator in the spectral action is made dynamical by introducing a dilaton field. We evaluate all the low-energy terms…
Applications of the Gauge Principle to Gravitational Interactions
Ali H. Chamseddine
The idea of applying the gauge principle to formulate the general theory of relativity started with Utiyama in 1956. I review various applications of the gauge principle applied to…
Caustics in Dark Matter Haloes
Roya Mohayaee, Stephane Colombi, Bernard Fort +3
Caustics are formally singular structures, with infinite density, that form in collisionless media. The non-negligible velocity dispersion of dark matter particles renders their de…
General Supersymmetric Solutions of Five-Dimensional Supergravity
Jan B. Gutowski, Wafic Sabra
The classification of 1/4-supersymmetric solutions of five dimensional gauged supergravity coupled to arbitrary many abelian vector multiplets, which was initiated in hep-th/040112…
Hermitian Geometry and Complex Space-Time
Ali H. Chamseddine
We consider a complex Hermitian manifold of complex dimensions four with a Hermitian metric and a Chern connection. It is shown that the action that determines the dynamics of the…
GL(1) Charged States in Twistor String Theory
Dimitri Polyakov
We discuss the appearance of the GL(1) charged physical operators in the twistor string theory. These operators are shown to be BRST-invariant and non-trivial, and some of their co…
