Fractal properties of SDSS quasars
IK Rozgacheva, AA Agapov - arXiv preprint arXiv:1101.4280, 2011 - arxiv.org
The distribution of SDSS quasars is described. The dependence of observational number of
quasars within distances to an observer less than r on distance r is found to be the power
law with correlation dimension value equal 2, 71 in redshift range 0, 35< z< 2, 30 for the flat …

The fractal cosmological model
IK Rozgacheva, AA Agapov - arXiv preprint arXiv:1103.0552, 2011 - arxiv.org
The fractal cosmological model which accounts for observable fractal properties of the
Universe's large-scale structure is constructed. In this framework these properties are
consequences of the rotary symmetry of charged scalar meson matter field (complex field) …

Role of massive neutrinos in the evolution of gravitational cosmological disturbances
IK Rozgacheva - Astronomicheskij Zhurnal, 1984 - inis.iaea.org
Gravitational perturbations of a standard model of the Universe filled by weakly interacting
neutrinos and photon plasma are considered. Accounting for density pepturbations of the
neutrino gas alteps the law of evolution of plasma adiabatic perturbations. It is shown that …

Model of laminar convection in solar type stars
IK Rozgacheva, EA Bruevich - Astronomical and Astrophysical …, 2002 - Taylor & Francis
We present a new model of large-scale multilayer convection in solar type stars. This model
allows us to understand such self-similar structures observed at solar surface as granulation,
supergranulation and giant cells. We study the slow-rotated hydrogen star without magnetic …

[PDF][PDF] A doubly-connected cosmological model
IK Rozgacheva - Astronomy Reports, 1997 - researchgate.net
A uniform, isotropic cosmological model filled by scalar and pseudoscalar fields subject to
chiral symmetry is described. The model is nonsingular, topologically compact and
possesses particlelike properties. Space-time is two-sheeted. The model is doubly …

Collective dynamics of density fluctuations in a gravitating medium
IK Rozgacheva - Astrophysics, 1988 - Springer
The evolution of a density inhomogeneity in a gravitating medium is considered with
allowance for the influence of surrounding inhomogeneities. It is shown that the collective
gravitational field of the fluctuations can significantly change the rate of evolution of density …
