We develop a new approach to gravitational waves in which the Einstein equations are
governed by the cosmological constant which is related to the existence of a manifold which …

We investigate, in the context of five-dimensional (5D) Brans–Dicke theory of gravity, the
idea that macroscopic matter configurations can be generated from pure vacuum in five …

We follow the approach of induced-matter theory for a five-dimensional (5 D) vacuum Brans–
Dicke theory and introduce induced-matter and induced potential in four dimensional (4 D) …

Using a formalism recently introduced we study the decaying of the cosmological parameter
during the early evolution of an universe, whose evolution is governed by a vacuum …

Gravitoelectromagnetic inflation was recently introduced to describe, in an unified manner,
electromagnetic, gravitatory and inflaton fields in the early (accelerated) inflationary universe …

In the framework of the induced matter theory of gravity, we derive a five-dimensional
solution of the field equations that can describe a four-dimensional cosmological scenario …

We develop a type of Kaluza–Klein formalism in (4+ 4)-dimensions. In the framework of this
formalism, we obtain a new kind of Schwarzschild metric solution that, via Kruskal …

We revisit an extension of the well-known formalism for gauge-invariant scalar metric
fluctuations to study the spectra for both the inflaton and gauge-invariant (scalar) metric …

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 …
