摘要：
In this paper it is shown that the Brans – Dicke scalar field itself can serve the purpose of providing an early deceleration and a late time acceleration of the universe without any need of quintessence field if one considers an interaction, i.e., transfer of energy between the dark matter and the Brans – Dicke scalar field.
