Unified Inflation with dark energy in the holographic model of Nojiri-Odintsov

The unification of the early and late-time universe on the basis of the holographic principle, taking into account the properties of the viscosity of the fluid in the spatial metric of Friedman - Lemeter - Robertson - Walker is considered. The description is uses the idea of a generalized cut-off of holographic dark energy proposed by Nojiri and Odintsov. To study the evolution of the unified universe, a generalized equation of state of a dark fluid is applied, including two asymptotic cases. As an example, a cosmological model with a constant thermodynamic parameter and a constant bulk viscosity is studied. Analytical expression for infrared radius in terms of the particle horizon and the energy conservation law from a holographic point of view are obtained. A viscous fluid describing the unifying description of the early and late-time universe is represented as a generalized holographic energy.
