Özet
İngilizce (OpenAlex)
We study cosmological scenarios of the polytropic gas (PG) dark matter-energy proposal in a Friedmann–Robertson–Walker (FRW) Universe. As a first step, we obtain an exact expression for the energy density of PG model by making use of the thermodynamics. Later, we investigate some cosmological quantities and perform neo-classical analyzes. Finally, we implement a connection between the PG and a homogenous minimally coupled scalar field by introducing its self-interacting potential.
