dc.description.abstract |
We establish a general thermodynamic scheme for cosmic fluids with internal self-interactions and discuss equilibrium and non-equilibrium aspects of such systems in connection with (generalized) symmetry properties of the cosmological dynamics. As an example we construct an exactly solvable gas dynamical model of a "deflationary" transition from an initial de Sitter phase to a subsequent Friedmann-Lemaître-Robertson-Walker period. We demonstrate that this dynamics represents a manifestation of a conformal symmetry of an "optical" metric, characterized by a specific effective refraction index of the cosmic medium. ©2000 The American Physical Society. |
