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…
Scalar-tensor analysis of an exponential Lagrangian for the Gravitational Field
O. M. Lecian, G. Montani
Within the scheme of modified gravity, an exponential Lagrangian density will be considered, and the corresponding scalar-tensor description will be addressed for both positive and…
Dark Energy as a Relic of the Vacuum-Energy Cancellation?
O. M. Lecian, G. Montani
We analyze the dynamical implications of an exponential Lagrangian density for the gravitational field, as referred to an isotropic FRW Universe. Then, we discuss the features of t…
