G2–cosmologies with perfect fluid in dilaton gravity
نویسنده
چکیده
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.

Geodesically complete nondiagonal inhomogeneous cosmological solutions in dilatonic gravity with a stiff perfect fluid
New nondiagonal G2 inhomogeneous cosmological solutions are presented in a wide range of scalar-tensor theories with a stiff perfect fluid as a matter source. The solutions have no big-bang singularity or any other curvature singularities. The dilaton field and the fluid energy density are regular everywhere, too. The geodesic completeness of the solutions is investigated. 04.50.+h, 04.20.Jb, 9...

متن کاملOn Average Properties of Inhomogeneous Fluids in General Relativity: Perfect Fluid Cosmologies
For general relativistic spacetimes filled with an irrotational perfect fluid a generalized form of Friedmann’s equations governing the expansion factor of spatially averaged portions of inhomogeneous cosmologies is derived. The averaging problem for scalar quantities is condensed into the problem of finding an ‘effective equation of state’ including kinematical as well as dynamical ‘backreacti...
متن کاملString Dilaton Fluid Cosmology
We investigate (n+ 1)-dimensional string-dilaton cosmology with effective dilaton potential in presence of perfect-fluid matter. We get exact solutions parametrized by the constant γ of the state equation p = (γ−1)ρ, the spatial dimension number n, the bulk of matter, and the spatial curvature constant k. Several interesting cosmological behaviours are selected. Finally we discuss the recoverin...

We present a new exact perfect fluid interior solution for a particular scalartensor theory. The solution is regular everywhere and has a well defined boundary where the fluid pressure vanishes. The metric and the dilaton field match continuously the external solution. Exact solutions provide a route to better and more deep understanding of the inherent nonlinear character of gravity. One of th...
