Asymptotic Freedom Cosmology
For a general class of scalar–tensor gravity theories, we discuss how to recover asymptotic freedom regimes when cosmic time t → ±∞. Such a feature means that the effective gravitational coupling Geff → 0, while cosmological solutions can asymptotically assume de Sitter or power–law behaviours. In our opinion, through this mechanism, it is possible to cure some shortcomings in inflationary and ...
متن کاملAsymptotic Freedom from Induced Gravity Cosmology
We give conditions to obtain cosmological asymptotic freedom in scalar–tensor theories of gravity. We show that this feature can be achieved in FRW flat spacetimes since we obtain singularity free solutions where the effective gravitational constant Geff → 0 for t → −∞ and, for some of them, Geff → GN for t → ∞, where GN is the Newton constant.

متن کاملAsymptotic Freedom 1. Understanding Asymptotic Freedom in Qcd
I discuss how the basic phenomenon of asymptotic freedom in QCD can be understood in elementary physical terms. Similarly, I discuss how the long-predicted phenomenon of “gluonization of the proton” – recently spectacularly confirmed at HERA – is a rather direct manifestation of the physics of asymptotic freedom. I review the broader significance of asymptotic freedom in QCD in fundamental phys...
متن کاملAsymptotic Flatness in Rainbow Gravity
A construction of conformal infinity in null and spatial directions is constructed for the Rainbow-flat space-time corresponding to doubly special relativity. From this construction a definition of asymptotic DSRness is put forward which is compatible with the correspondence principle of Rainbow Gravity. Furthermore a result equating asymptotically flat space-times with asymptotically DSR space...
متن کاملAsymptotic Flatness, Little String Theory, and Holography
We argue that any non-gravitational holographic dual to asymptotically flat string theory in d-dimensions naturally resides at spacelike infinity. Since spacelike infinity can be resovled as a (d − 1)-dimensional timelike hyperboloid (i.e., as a copy of de Sitter space in (d− 1) dimensions), the dual theory is defined on a Lorentz signature spacetime. Conceptual issues regarding such a duality ...
