Rotating and spatially twisting Locally Rotationally Symmetric Spacetimes in f(R)-Gravity: a No-Go theorem
Sayuri Singh, Amare Abebe, Rituparno Goswami +1
Recently, in a series of papers, we established the existence and found a general solution for the simultaneously rotating and twisting locally rotationally symmetric spacetimes in…
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 gravity in scalar-tensor theories
Joseph Ntahompagaze, Amare Abebe, Manasse Mbonye
We study gravity models in the language of scalar-tensor theories. The correspondence between gravity and scalar-tensor theories is revisited since 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 gravity from the Chaplygin scalar field in flat de Sitter spacetimes. Exploiting the equivalence between gravity a…
