Description

The four-dimensional flat Friedman universe filled with an ideal fluid with a linear (oscillating) inhomogeneous equation of state (EoS) depending on time is studied. The equations of motion are solved. It is shown that in some cases there appears a quasi-periodical universe that repeats the cycles of phantom-type space acceleration. The appearance of future singularities resulting from various choices for the input parameters is discussed. (orig.)
