Dark energy with special form inhomogeneous equation of state

Timoshkin Aleksandr Vasilyevich

Information About Author:

The four-dimensional flat Friedman universe filled with ideal fluid with a nonlinear inhomogeneous equation of state depending on time is considered. The equations of motion are solved. It is shown that in some cases there appears a quasi-periodical universe. On the other hand, such dark fluid models may also describe quintessence-like cosmic acceleration. The appearance of future singularities resulting from various choices for the input parameters is discussed.
