In this paper, we review the so-called Myrzakulov Gravity models (MG-N, with N= I, II,…, VIII)
and derive their respective metric-affine generalizations (MAMG-N), discussing also their …

General relativity (GR) exists in different formulations, which are equivalent in pure gravity.
Once matter is included, however, observable predictions generically depend on the version …

General relativity (GR) exists in different formulations. They are equivalent in pure gravity but
generically lead to distinct predictions once matter is included. After a brief overview of …

We construct a theory of gravity in which a propagating massive vector field arises from a
quadratic curvature invariant. The Einstein-Cartan formulation and a partial suppression of …

We derive the full set of field equations for the metric-affine version of the Myrzakulov gravity
model and also extend this family of theories to a broader one. More specifically, we …

We investigate the cosmological aspects of the most general parity preserving Metric-Affine
Gravity theory quadratic in torsion and nonmetricity in the presence of a cosmological …

We construct a theory of gravity in which a propagating massive vector field arises from a
quadratic curvature invariant. The Einstein-Cartan formulation and a partial suppression of …

It is well-known that the Einstein-Hilbert action exhibits a projective invariance in metric-
affine gravity, generated by a single vector (just like diffeomorphisms). However, this …

We study a cosmological model based on the canonical Hamiltonian transformation theory.
Using a linear-quadratic approach for the free gravitational De Donder–Weyl …

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) …
