Wei, Yihuan Extended complex scalar field as a quintessence. (English) Zbl 1057.83026 Gravit. Cosmol. 9, No. 4(36), 307-310 (2003). Summary: We show the possibility that an extended complex scalar field can be considered as an extended complex quintessence model. For this model, we derive the basic equations with a parameter \(\eta\) which govern the evolution of the Universe. Our model may contain a complex quintessence model for \(\eta=-1\) and a real quitessence model for \(\eta=0\).
