Abstract

The generalized Brans-Dicke cosmology is studied. We find that the difference in the evolution of the universe is significant between the generalized Brans-Dicke cosmology and the standard cosmology during the radiation-dominated era and the inflationary era, though the difference is negligible during the matter-dominated era. The consequences arising from the differences remain to be studied in detail.
