摘要：
The effects of quantum gravity at very high energy are necessary to modify the thermodynamics of the early universe. Hence the generalized dispersion relation, as a general characteristic of all theories of quantum gravity, provides the framework for a modification in the thermodynamics of the universe. Here, using the generalized dispersion relation and the modified entropy we employ a cosmological vector field model to obtain the generalized Friedmann equation.
