Riemannian and non-Riemannian extensions of geometrodynamics versus Einsteinian gravity
O. M. Lecian, G. Montani
We analyze some extensions of General Relativity. Within the framework of modified gravity, the Newtonian limit of a class of gravitational actions is discussed on the basis of the…
Extended Schouten classification for non-Riemannian geometries
S. Casanova, O. M. Lecian, G. Montani +2
A generalized connection, including Christoffel coefficients, torsion, non-metricity tensor and metric-asymmetricity object, is analyzed according to the Schouten classification. T…
Macroscopic and Microscopic Paradigms for the Torsion Field: from the Test-Particle Motion to a Lorentz Gauge Theory
Nakia Carlevaro, Orchidea Maria Lecian, Giovanni Montani
Torsion represents the most natural extension of General Relativity and it attracted interest over the years in view of its link with fundamental properties of particle motion. The…
Classical and Quantum Features of the Mixmaster Singularity
Giovanni Montani, Marco Valerio Battisti, Riccardo Benini +1
This review article is devoted to analyze the main properties characterizing the cosmological singularity associated to the homogeneous and inhomogeneous Mixmaster model. After the…
Study of the Quasi-isotropic Solution near the Cosmological Singularity in Presence of Bulk-Viscosity
Nakia Carlevaro, Giovanni Montani
We analyze the dynamical behavior of a quasi-isotropic Universe in the presence of a cosmological fluid endowed with bulk viscosity. We express the viscosity coefficient as a power…
Minisuperspace dynamics in a generalized uncertainty principle framework
Marco Valerio Battisti, Giovanni Montani
The minisuperspace dynamics of the Friedmann-Robertson-Walker (FRW) and of the Taub Universes in the context of a Generalized Uncertainty Principle is analyzed in detail. In partic…
