Improved Action Functionals in Non-Perturbative Quantum Gravity
Alfio Bonanno, Giampiero Esposito, Claudio Rubano
Models of gravity with variable G and Lambda have acquired greater relevance after the recent evidence in favour of the Einstein theory being non-perturbatively renormalizable in t…
Dark energy exponential potential models as curvature quintessence
S. Capozziello, V. F. Cardone, E. Piedipalumbo +1
It has been recently shown that, under some general conditions, it is always possible to find a fourth order gravity theory capable of reproducing the same dynamics of a given dark…
The Accelerated expansion of the Universe as a crossover phenomenon
A. Bonanno, G. Esposito, C. Rubano +1
We show that the accelerated expansion of the Universe can be viewed as a crossover phenomenon where the Newton constant and the Cosmological constant are actually scaling operator…
