Quasi-isotropic expansion for a two-fluid cosmological model containing radiation and string gas
I. M. Khalatnikov, A. Yu. Kamenshchik, A. A. Starobinsky
The quasi-isotropic expansion for a simple two-fluid cosmological model, including radiation and string gas is constructed. The first non-trivial order expressions for the metric c…
Some properties of the "String gas" with the equation of state
Alexander Yu. Kamenshchik, Isaak M. Khalatnikov
We show that the string gas - a perfect fluid with the equation of state possesses rather interesing properties. In Friedmann universes its presence can can change…
Relativistic hodograph equation for a two-dimensional stationary isentropic hydrodynamical motion
I. Khalatnikov, A. Kamenshchik
We derive a relativistic hodograph equation for a two-dimensional stationary isentropic hydrodynamical motion. For the case of stiff matter, when the velocity of sound coincides wi…

Quasi-isotropic solution of the Einstein equations near a cosmological singularity for a two-fluid cosmological model
I. M. Khalatnikov, A. Yu. Kamenshchik, M. Martellini +1
The quasi-isotropic inhomogeneous solution of the Einstein equations near a cosmological singularity in the form of a series expansion in the synchronous system of reference, first…
A generalisation of the Heckmann - Schucking cosmological solution
I. M. Khalatnikov, A. Yu. Kamenshchik
An exact solution of the Einstein equations for a Bianchi -I universe in the presence of dust, stiff matter and cosmological constant, generalising the well-known Heckmann-Schuckin…
