英文摘要: Whereas the recent observations of type Ia supentovae (SNe Ia) reveal the universe is accelerating, we show in this Letter the possibility of a coupled complex scalar field to be quintessence for the source of the accelerating universe. We obtain the main equations which govern. the evolution of the universe and rewrite them with the observable quantities. Finally we point out very briefly how future observations may determine the equation of state of quintessence. (C) 2002 Elsevier Science B.V. All rights reserved.
