Extended General Relativity: large-scale antigravity and short-scale gravity with ω=-1 from five dimensional vacuum
Jose Edgar Madriz Aguilar, Mauricio Bellini
Considering a five-dimensional (5D) Riemannian spacetime with a particular stationary Ricci-flat metric, we obtain in the framework of the induced matter theory an effective 4D sta…
The seed of magnetic monopoles in the early inflationary universe from a 5D vacuum state
Jesus Martin Romero, Mauricio Bellini
Starting from a 5D Riemann flat metric, we have induced an effective 4D Hermitian metric which has an antisymmetric part which is purely imaginary. We have worked an example in whi…
Primordial large-scale electromagnetic fields from Gravitoelectromagnetic Inflation
Federico Agustin Membiela, Mauricio Bellini
We investigate the origin and evolution of primordial electric and magnetic fields in the early universe, when the expansion is governed by a cosmological constant . Using the…
A confirmation of agreement of different approaches for scalar gauge-invariant metric perturbations during inflation
Mariano Anabitarte, Mauricio Bellini
We revisit an extension of the well-known formalism for gauge-invariant scalar metric fluctuations, to study the spectrums for both, the inflaton and gauge invariant (scalar) metri…
Phantom cosmology with a decaying cosmological function induced from five-dimensional (5D) geometrical vacuum
Jose Edgar Madriz Aguilar, Mauricio Bellini, Marco Aurelio S. Cruz
Introducing a variable cosmological function in a geometrical manner from a 5D Riemann-flat metric, we investigate the possibility of having a geometrical criterion to choos…
Metric fluctuations from a NKK theory of gravity in a de Sitter expansion
Jose Edgar Madriz Aguilar, Mauricio Bellini
A gauge invariant metric fluctuations formalism from a non-compact Kaluza-Klein (NKK) theory of gravity is presented in this talk notes. In this analysis we recover the well-known…
