Conformal invariance of curvature perturbation
Conformal invariance curvature perturbation
2011/7/10
We show that in the single component situation all perturbation variables in the comoving gauge are conformally invariant to all perturbation orders. Generally we identify a special time slicing, the ...
Fitting galactic rotation curves with conformal gravity and a global quadratic potential
galactic rotation conformal gravity global quadratic potential
2010/11/15
We apply the conformal gravity theory to a sample of 110 spiral galaxies whose rotation curve
data points extend well beyond the optical disk. With no free parameters other than galactic mass to ligh...
Conformal Cosmology and the Pioneer Anomaly
Cosmology and Extragalactic Astrophysics (astro-ph.CO) General Relativity and Quantum Cosmology (gr-qc)
2010/10/15
We review the fundamental results of a new cosmological model, based on conformal gravity, and apply them to the analysis of the early data of the Pioneer anomaly. We show that our conformal cosmology...
Boundary stress tensors for spherically symmetric conformal Rindler observers
surface energy conformal Rindler geometry horizon en-tropy equipartition law
2010/1/26
The boundary energy - momentum tensors for a static observer in the conformally flat Rindler geometry are considered. We found the surface energy is positive far form the Planck world but the transver...
On the final definition of the causal boundary and its relation with the conformal boundary
causal structure Kronheimer and Penrose construction chronological sets and completions causal boundary conformal boundary globally hyperbolic spacetimes naked singularities Penrose-Carter diagrams
2010/1/19
The notion of causal boundary $\partial M$ for a strongly causal spacetime $M$ has been a controversial topic along last decades: on one hand, some attempted definitions were not fully consistent, on ...
Gravity duals for logarithmic conformal field theories
Gravity duals Logarithmic conformal field
2009/12/30
Logarithmic conformal field theories with vanishing central charge describe systems with quenched disorder, percolation or dilute self-avoiding polymers. In these theories the energy momentum tensor a...
