Inflationary expansion of the universe with variable timescale
/ Musmarra, Juan Ignacio ; Anabitarte, Mariano ; Bellini, Mauricio
We explore a cosmological model in which the time scale is variable with the expansion of the universe and the effective spacetime is driven by the inflaton field. [...]

Preinflation: Origin of the Universe from a topological phase transition
/ Bellini, Mauricio
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. [...]

Geometric backreaction in preinflation from relativistic quantum geometry
/ Arcodía, Marcos R. A. ; Bellini, Mauricio
The preinflationary evolution of the universe describes the beginning of the expansion from a static initial state, such that the Hubble parameter is initially zero, but increases to an asymptotic constant value, in which it could achieve a de Sitter (inflationary) expansion. [...]

Towards relativistic quantum geometry
/ Ridao, Luis Santiago ; Bellini, Mauricio
We obtain a gaugeinvariant relativistic quantum geometry by using a Weylianlike manifold with a geometric scalar field which provides a gaugeinvariant relativistic quantum theory in which the algebra of the Weylianlike field depends on observers. [...]

WIMT in Gullstränd–Painlevé and Reissner–Nordström metrics: induced stable gravitomagnetic monopoles
/ Romero, Jesús Martín ; Bellini, Mauricio
The aim of this work is to apply Weitzeböck Induced Matter Theory (WIMT) to Gullstränd–Painlevé and Reissner–Nordström metrics in the framework of WIMT. [...]

Present accelerated expansion of the universe from new Weylintegrable gravity approach
/ Aguila, Ricardo ; Madriz Aguilar, José Edgar ; Moreno, Claudia ; Bellini, Mauricio
We investigate if a recently introduced formulation of general relativity on a Weylintegrable geometry contains cosmological solutions exhibiting acceleration in the present cosmic expansion. [...]

Gravitomagnetic currents in the inflationary universe from WIMT
/ Romero, Jesús Martín ; Bellini, Mauricio
Using the Weitzenböck representation of a Riemannflat 5D spacetime, we study the possible existence of primordial gravitomagnetic currents from Gravitoelectromagnetic Inflation (GEMI). [...]
