Stochastic cosmology, theories of perturbations and Lifshitz gravity
I. M. Khalatnikov, A. Yu. Kamenshchik
We review some works of E M Lifshitz connected with gravity and cosmology and also some later works, connected with his ideas. The main topics of this review are the stochastic cos…
Remarks on the method of comparison equations (generalized WKB method) and the generalized Ermakov-Pinney equation
A Kamenshchik, M Luzzi, G Venturi
The connection between the method of comparison equations (generalized WKB method) and the Ermakov-Pinney equation is established. A perturbative scheme of solution of the generali…
Comment about quasi-isotropic solution of Einstein equations near cosmological singularity
I. M. Khalatnikov, A. Yu. Kamenshchik, A. A. Starobinsky
We generalize for the case of arbitrary hydrodynamical matter the quasi-isotropic solution of Einstein equations near cosmological singularity, found by Lifshitz and Khalatnikov in…
Diagram technique for perturbation theory calculations of the effective conductivity of two-dimensional systems
I. M. Khalatnikov, A. Yu. Kamenshchik
The perturbation theory for calculation of the effective conductivity of the plane consisting of pieces of different conductivities is constructed and the convenient diagram techni…
