Inflationary f(R) cosmologies

Heba Sami, Joseph Ntahompagaze, Amare Abebe

This paper discusses a simple procedure to reconstruct f (R)-gravity models from exact cosmological solutions of the Einstein field equations with a noninteracting classical scalar…

On $f (R)$ gravity in scalar-tensor theories

Joseph Ntahompagaze, Amare Abebe, Manasse Mbonye

We study $f (R)$ gravity models in the language of scalar-tensor theories. The correspondence between $f (R)$ gravity and scalar-tensor theories is revisited since $f (R)$ gravity is…

Reconstructing f(R) Gravity from a Chaplygin Scalar Field in de Sitter Spacetimes

Heba Sami, Neo Namane, Joseph Ntahompagaze +2

We present a reconstruction technique for models of $f (R)$ gravity from the Chaplygin scalar field in flat de Sitter spacetimes. Exploiting the equivalence between $f (R)$ gravity a…
