Özet

We consider a cosmological model in which the early universe is dominated by the equation of state p = -rho/3 corresponding to a coasting cosmology. This equation of state was first obtained in the context of cosmic string theories whereas its one-parameter generalization describing a coasting early universe followed by a radiation-dominated universe was first derived from Kaluza-Klein theories based on Euler form actions. We show that in such a model the temperature is almost absolute zero at the beginning and the universe quickly heats up to maximum temperature.
