In this work we propose a preinflationary model that describes the birth of the universe with
nonzero spatial curvature, variable timescale and an initially null background energy …

I study a model which describes the birth of the universe using a global topological phase
transition with a complex manifold where the time, τ, is considered as a complex variable …

I study an extended theory of General Relativity that incorporates normalized relativistic
velocities, where the boundary terms in the varied f (R)-action are considered as a part of the …

In this work, we develop a model for the early universe in which preinflation is followed by a
warming epoch and a subsequent sub-exponential quintessential expansion. We …

In this paper, I propose a model to describe the birth of the universe taking into account back
reaction effects produced by the inflaton field fluctuations, with self-interactions included …

We study the interior of a Reissner–Nordström Black-Hole (RNBH) using Relativistic
Quantum Geometry, which was introduced in some previous works. We found discrete …

Using the Gödel metric, we obtain some relevant solutions compatible with spatiotemporal
jumps for the geodesic equations, by using an extension of General Relativity with nonzero …

We propose a unified theory for spinor fields on extended Weyl manifolds taking into
account self-interactions to obtain the relativistic dynamics on a general curved Riemannian …

Abstract Using Relativistic Quantum Geometry (RQG), we study the emergence of back-
reaction modes with solitonic properties, on astrophysical and cosmological scales, in a …

In this work, we develop a model for the early universe in which preinflation is followed by a
warming epoch and a subsequent sub-exponential quintesential expansion. We …
