A Review on attempts to propose alternative theories to the General Relativity is presented.
The restriction is on classical models/theories and comprise rather algebraic extensions of …

In this paper, we review classical and quantum field theory of massive non-interacting spin-
two fields. We derive the equations of motion and Fierz–Pauli constraints via three different …

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

In this paper, the generic part of the gauge theory of gravity is derived, based merely on the
action principle and on the general principle of relativity. We apply the canonical …

We use the conditional symmetry approach to study the r evolution of a minisuperspace
spherically symmetric model both at the classical and the quantum level. After integration of …

The cosmological implications of the covariant canonical gauge theory of gravity (CCGG)
are investigated. We deduce that, in a metric-compatible geometry, the requirement of …

The generic form of space-time dynamics as a classical gauge field theory has recently been
derived, based on only the action principle and on the principle of general relativity. It was …

The covariant canonical transformation theory applied to the relativistic Hamiltonian theory
of classical matter fields in dynamical space-time yields a novel (first order) gauge field …

Abstract Constraints on the Covariant Canonical Gauge Gravity (CCGG) theory from low-
redshift cosmology are studied. The formulation extends Einstein's theory of General …

In this study we prove that the Pauli interaction—which is associated with a length parameter—
emerges when the minimal coupling recipe is applied to the non-degenerate version of the …
