We analyze characteristic properties of two different cosmological models:(i) a one-
component dark energy model where the bulk viscosity ζ is associated with the fluid as a …

In this paper, we will consider a phenomenological model of a dark fluid that is able to
explain an accelerated expansion of our low redshift universe and the phase transition to …

The goal of this paper is to study new cosmological models where the dark energy is a
varying Chaplygin gas. This specific dark energy model with non-linear EoS had been often …

In this paper we study interacting generalized cosmic Chaplygin gas with bulk viscosity for
Kaluza-Klein type FRW metric in the frame work of general theory of relativity. We consider …

The recent method of conservation laws for constructing exact solutions of partial differential
equations is applied to the nonlocal conservation laws of the Chaplygin gas. The nonlocal …
