On Chaplygin models in f(G) gravity
Fidele Twagirayezu, Abraham Ayirwanda, Albert Munyeshyaka +3
The current work treats cosmological perturbation in a mixture of standard matter, Chaplygin gas as well as Gauss-bonnet fluids using a 1+3 covariant approach in the context of mod…
Perturbations in the interacting vacuum
Albert Munyeshyaka, Joseph Ntahompagaze, Tom Mutabazi +4
In this study, we present the evolution of cosmological perturbations in a universe consisting of standard matter and interacting vacuum. We use the covariant formalism in…
Multifluid cosmology in f (G) gravity
Albert Munyeshyaka, Abraham Ayirwanda, Fidele Twagirayezu +1
The treatment of 1 + 3 covariant perturbation in a multifluid cosmology with the consideration of f (G) gravity, G being the Gauss-Bonnet term, is done in the present paper. We def…
On inflationary parameters in scalar-tensor theories
Beatrice Murorunkwere, Fidele Twagirayezu, Albert Munyeshyaka +2
The equivalence between and scalar-tensor theories is revisited, we consequently explored different models. After consideration of specific definition of the scalar f…
