Isotropic singularities in shear-free perfect fluid cosmologies
We investigate barotropic perfect fluid cosmologies which admit an isotropic singularity. From the General Vorticity Result of Scott, it is known that these cosmologies must be irrotational. In this paper we prove, using two different methods, that if we make the additional assumption that the perfect fluid is shear-free, then the fluid flow must be geodesic. This then implies that the only she...
متن کاملFuture Singularities of Isotropic Cosmologies
We show that globally and regularly hyperbolic future geodesically incomplete isotropic universes, except for the standard all-encompassing ‘big crunch’, can accommodate singularities of only one kind, namely, those having a non-integrable Hubble parameter, H. We analyze several examples from recent literature which illustrate this result and show that such behaviour may arise in a number of di...
متن کاملIsotropic Cosmological Singularities I. Polytropic Perfect Fluid Spacetimes
We consider the conformal Einstein equations for 1 ≤ γ ≤ 2 poly-tropic perfect fluid cosmologies which admit an isotropic singularity. For 1 < γ ≤ 2 it is shown that the Cauchy problem for these equations is well-posed, that is to say that solutions exist, are unique and depend smoothly on the data, with data consisting of simply the 3-metric of the singularity. The analogous result for γ = 1 (...
متن کاملPerfect fluid cosmologies with varying light speed
We have found exact constant solutions for the cosmological density parameter using a generalization of general relativity that incorporates a cosmic time-variation of the velocity of light in vacuum and the Newtonian gravitation constant. We have determined the conditions when these solutions are attractors for an expanding universe and solved the problems of the Standard Big Bang model for pe...
متن کاملG2–cosmologies with perfect fluid in dilaton gravity
We present a method for generating exact diagonal G2-cosmological solutions in dilaton gravity coupled to a radiation perfect fluid and with a cosmological potential of a special type. The method is based on the symmetry group of the system of G2-field equations. Several new classes of explicit exact inhomogeneous perfect fluid scalar-tensor cosmologies are presented.
