Cosmological dynamics of fourth order gravity: A compact view
Mohamed Abdelwahab, Rituparno Goswami, Peter K. S. Dunsby
We construct a compact phase space for flat FLRW spacetimes with standard matter described by a perfect fluid with a barotropic equation of state for general f(R) theories of gravi…

Covariant gauge-invariant perturbations in multifluid f(R) gravity
Amare Abebe, Mohamed Abdelwahab, Alvaro de la Cruz-Dombriz +1
We study the evolution of scalar cosmological perturbations in the (1+3)- covariant gauge-invariant formalism for generic theories of gravity. Extending previous works, we g…
