The quantization of gravity and the vacuum energy of quantum fields
We construct a unified covariant derivative that contains the sum of an affine connection and a Yang-Mills field. With it we construct a lagrangian that is invariant both under diffeomorphisms and
Fundamental Symmetries and Spacetime Geometries in Gauge Theories of Gravity—Prospects for Unified Field Theories
Gravity can be formulated as a gauge theory by combining symmetry principles and geometrical methods in a consistent mathematical framework. The gauge approach to gravity leads directly to
Torsion waves in metric-affine field theory
The approach of metric-affine field theory is to define spacetime as a real oriented 4-manifold equipped with a metric and an affine connection. The 10 independent components of the metric tensor and
Tensor-Tensor Theory of Gravitation
We consider the standard gauge theory of Poincare group, realizing as a subgroup of $GL(5. R)$. The main problem of this theory was appearing of the fields connected with non-Lorentz symmetries,
Poincare gauge theory of gravity: Friedman cosmology with even and odd parity modes. Analytic part
We propose a cosmological model in the framework of the Poincare gauge theory of gravity (PG). The gravitational Lagrangian is quadratic in both curvature and torsion. In our specific model, the
(Super)conformal gravity with totally antisymmetric torsion
We present a gauge theory of the conformal group in four spacetime dimensions with a non-vanishing torsion. In particular, we allow for a completely antisymmetric torsion, equivalent by Hodge duality

We are interested in constitutive theory under the influence of gravitation. General Relativity Theory (GRT) using Riemann geometry for geometrization of the gravitation force is currently assumed to
Metric-affine gravity and inflation
We classify the metric-affine theories of gravitation, in which the metric and the connections are treated as independent variables, by use of several constraints on the connections. Assuming the

We consider the most general quadratic metric-affine gravity setup in the presence of generic matter sources with non-vanishing hypermomentum. The gravitational action consists of all 17 quadratic
A new framework for perturbative quantum gravity is proposed following the geometry of non-holonomic distributions on (pseudo)Riemannian manifolds. There are considered such distributions and


Gravity and the Poincaré group.
The field equations for the gauge potentials, for pointlike sources, and for scalar and spinor matter fields reproduce the Einstein equations, the geodesics equations, and the Klein-Gordon and the Dirac equations in curved space-time, respectively.
Gauge fields, space-time geometry and gravity
A general framework for the gauge theory of the affine group and its various subgroups in terms of connections on the bundle of affine frames and its subbundles is given, with emphasis on the correct
Hamiltonian Structure of Poincaré Gauge Theory and Separation of Non-Dynamical Variables in Exact Torsion Solutions
The canonical Hamiltonian of the Poincare gauge theory of gravity is reanalyzed for generic Lagrangians. It is shown that the time components e0α and Γ0αβ of the tetrad and the linear connection
Spin and the structure of space-time
The gravitational field in General Relativity (GR) is coupled to the energy-momentum tensor of matter, i. e. it is the dynamical manifestation of energy-momentum. In Section 1 we try to collect all
