Bianchi Cosmological Models and Gauge Symmetries
We analyze carefully the problem of gauge symmetries for Bianchi models, from both the geometrical and dynamical points of view. Some of the geometrical definitions of gauge symmetries (=“homogeneity preserving diffeomorphisms”) given in the literature do not incorporate the crucial feature that local gauge transformations should be independent at each point of the manifold of the independent v...
متن کاملOn the Integrability of Bianchi Cosmological Models
In this work, we are investigating the problem of integrability of Bianchi class A cosmological models. This class of systems is reduced to the form of Hamiltonian systems with exponential potential forms. The dynamics of Bianchi class A models is investigated through the EulerLagrange equations and geodesic equations in the Jacobi metric. On this basis, we have come to some general conclusions...
متن کاملConditional Symmetries and the Quantization of Bianchi Type I Vacuum Cosmologies with and without Cosmological Constant
In this work, the quantization of the most general Bianchi Type I geometry, with and without a cosmological constant, is considered. In the spirit of identifying and subsequently removing as many gauge degrees of freedom as possible, a reduction of the initial 6–dimensional configuration space is presented. This reduction is achieved by imposing as additional conditions on the wave function, th...
متن کاملDiscrete Symmetries in Translation Invariant Cosmological Models
In this paper we investigate a class of (d+1) dimensional cosmological models with a cosmological constant possessing an R simply transitive symmetry group and show that it can be written in a form that manifests the effect of a permutation symmetry. We investigate the solution orbifold and calculate the probability of a certain number of dimensions that will expand or contract. We use this to ...
متن کاملOn Bianchi Type Cosmological Models in Lyra’s Geometry
EYL [1] first try to unify gravitation and electromagnetism in single space-time geometry. He showed how one can introduce vector field in the Riemannian space time with an intrinsic geometric significance, but this theory was not accepted. Later Lyra’s [2] proposed a modification of Riemannian geometry by introducing a gauge function into the structureless manifold that bears close resemblance...
