Abstract

The scalar field model of dark energy is established in the doublecomplex symmetric gravitational theory. The universe we live in is takenas the real part of double complex space ℳC4(J). The twocases of scalar field (ordinary and phantom scalar field) are discussedin a unified way. Not only can the double Friedmann equations beobtained, but also the equation of state for dark energy, potentialV(ϕ) and scalar field ϕ can be expressed. Hence, a new methodis proposed to study dark energy and the evolution of the universe.
