Unifying the study of background dynamics and perturbations in -gravity
Sante Carloni, Kishore N. Ananda, Peter K. S. Dunsby +1
In this paper we show how the covariant gauge invariant equations for the evolution of scalar, vector and tensor perturbations for a generic -gravity theory can be recast in…
A characteristic signature of fourth order gravity
Kishore N. Ananda, Sante Carloni, Peter K. S. Dunsby
We present for the first time the complete matter power spectrum for gravity which has been derived from the fourth order scalar perturbation equations. This leads to the dis…
Curvature quintessence matched with observational data
S. Capozziello, V. F. Cardone, S. Carloni +1
Quintessence issues can be achieved by taking into account higher order curvature invariants into the effective action of gravitational field. Such an approach is naturally related…
Quintessence without scalar fields
S. Capozziello, S. Carloni, A. Troisi
The issues of quintessence and cosmic acceleration can be discussed in the framework of theories which do not include necessarily scalar fields. It is possible to define pressure a…
