Аннотация
Solutions of the cosmological model are considered within the framework of the modified Jordan–Brans–Dicke theory with a cosmological scalar. A special solution of the model describing an exponential expansion at the early stages and a power-law decelerating expansion at late stages is found. A comparison of the expansion features in the Jordan and Einstein representations is made. At the late stages of the evolution, the scale factor in the Jordan representation tends to a finite value.
