Sigma Models in Supergravity: Bianchi type IX Instantons and Cosmologies
We find instanton/cosmological solutions with biaxial Bianchi-IX symmetry, involving nontrivial spatial dependence of the CP and CP -sigma-models coupled to gravity. Such manifolds arise in N = 1, d = 4 supergravity with supermatter actions and hence the solutions can be embedded in supergravity. There is a natural way in which the standard coordinates of these manifolds can be mapped into the ...
متن کاملSymbolic Dynamics, Modular Curves, and Bianchi IX Cosmologies
It is well known that the so called Bianchi IX spacetimes with SO(3)–symmetry in a neighbourhood of the Big Bang exhibit a chaotic behaviour of typical trajectories in the backward movement of time. This behaviour (Mixmaster Model of the Universe) can be encoded by the shift of two–sided continued fractions. Exactly the same shift encodes the sequences of intersections of hyperbolic geodesics w...
متن کاملThe Bianchi Ix Attractor
We consider the asymptotic behaviour of spatially homogeneous spacetimes of Bianchi type IX close to the singularity (we also consider some of the other Bianchi types, e. g. Bianchi VIII in the stiff fluid case). The matter content is assumed to be an orthogonal perfect fluid with linear equation of state and zero cosmological constant. In terms of the variables of Wainwright and Hsu, we have t...
متن کاملHamiltonian reduction of Bianchi Cosmologies
It was noted recently that the ADM-diffeomorphism-constraint does not generate all observed symmetries for several Bianchi-models. We will suggest not to use the ADM-constraint restricted to homogeneous variables, but some equivalent which is derived from a restricted action principle. This will generate all homogeneity preserving diffeomorphisms, which will be shown to be automorphism generati...
متن کاملScale factor duality in string Bianchi cosmologies
We apply the scale factor duality transformations introduced in the context of the effective string theory to the anisotropic Bianchi-type models. We find dual models for all the Bianchi-types [except for types V III and IX] and construct for each of them its explicit form starting from the exact original solution of the field equations. It is emphasized that the dual Bianchi class B models req...
