Qualitative evolution in f(R) cosmologies
R. M. Avagyan, E. V. Chubaryan, G. H. Harutyunyan +1
We investigate the qualitative evolution of (D+1)-dimensional cosmological models in f(R) gravity for the general case of the function f(R). The analysis is specified for various e…
Interacting Quintessence Models of Dark Energy
M. Khurshudyan, E. Chubaryan, B. Pourhassan
In this paper we consider two models of quintessence scalar fields with different potentials. Interaction with generalized cosmic Chaplygin gas is also investigated. Cosmological p…
Phenomenologically varying and a toy model for the Universe
M. Khurshudyan, J. Sadeghi, E. Chubaryan +1
We consider a model of the Universe with variable G and Λ. Subject of our interest is a phenomenological model for Λ proposed and considered in this article first time (up to our k…
''Homogeneous'' Gravitational Field in General Relativity ?
R. M. Avakyan, E. V. Chubaryan, A. H. Yeranyan
The gravitation field of the flat plate was investigated. It have been shown that there exist the internal solution of Einstein equations sewed together with external one, which de…
