A study of perturbations in scalar-tensor theory using 1+3 covariant approach
Joseph Ntahompagaze, Amare Abebe, Manasse R. Mbonye
This work discusses scalar-tensor theories of gravity, with a focus on the Brans-Dicke subclass, and one that also takes note of the latter's equivalence with gravitation th…
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…
