Perspectives in Cosmology, Gravitation and Multidimensions
Giovanni Montani, Nakia Carlevaro, Francesco Cianfrani +1
Recent developments from the activity of the CGM Group are discussed. Cosmological implications of fundamental approaches to quantization of gravity are presented in order to fix t…
Lorentz Gauge Theory and Spinor Interaction
Nakia Carlevaro, Orchidea Maria Lecian, Giovanni Montani
A gauge theory of the Lorentz group, based on the different behavior of spinors and vectors under local transformations, is formulated in a flat space-time and the role of the tors…
On the Role of Viscosity in Early Cosmology
Nakia Carlevaro, Giovanni Montani
We present a discussion of the effects induced by bulk viscosity on the very early Universe stability. The viscosity coefficient is assumed to be related to the energy density …
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…
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…
Gravitational Stability and Bulk Cosmology
Nakia Carlevaro, Giovanni Montani
We present a discussion of the effects induced by bulk viscosity either on the very early Universe stability and on the dynamics associated to the extreme gravitational collapse of…
