Cosmology of Metric-Affine Gravity with Pure Shear Hypermomentum
Damianos Iosifidis, Ratbay Myrzakulov, Lucrezia Ravera
In this paper we study the cosmological aspects of metric-affine gravity with hyperfluid. The equations of motion of the theory are obtained by varying the action with respe…
Metric-Affine Vector-Tensor Correspondence and Implications in gravity
Damianos Iosifidis, Ratbay Myrzakulov, Lucrezia Ravera +2
We extend the results of antecedent literature on quadratic Metric-Affine Gravity by studying a new quadratic gravity action in vacuum which, besides the usual (non-Riemannian) Ein…
Cosmology of Quadratic Metric-Affine Gravity
Damianos Iosifidis, Lucrezia Ravera
We investigate the cosmological aspects of the most general parity preserving Metric-Affine Gravity theory quadratic in torsion and non-metricity in the presence of a cosmological…
Metric-Affine Myrzakulov Gravity Theories
N. Myrzakulov, R. Myrzakulov, L. Ravera
In this paper we review the Myrzakulov Gravity models (MG-N, with ) and derive their respective metric-affine generalizations (MAMG-N), discussing…
The Cosmology of Quadratic Torsionful Gravity
Damianos Iosifidis, Lucrezia Ravera
We study the cosmology of a quadratic metric-compatible torsionful gravity theory in the presence of a perfect hyperfluid. The gravitational action is an extension of the Einstein-…
Parity Violating Metric-Affine Gravity Theories
Damianos Iosifidis, Lucrezia Ravera
We study a parity violating Metric-Affine gravitational theory given by the Einstein-Hilbert action plus the so-called Holst term in vacuum. We find out that for a certain value of…
Einstein manifolds with torsion and nonmetricity
Dietmar Silke Klemm, Lucrezia Ravera
Manifolds endowed with torsion and nonmetricity are interesting both from the physical and the mathematical points of view. In this paper, we generalize some results presented in t…
