# DILATON COUPLED QUINTESSENCE MODEL IN THE ω - ω′ PLANE

@article{Huang2007DILATONCQ, title={DILATON COUPLED QUINTESSENCE MODEL IN THE $\omega$ - $\omega$′ PLANE}, author={Z. G. Huang and H. Q. Lu and Wei Fang}, journal={International Journal of Modern Physics D}, year={2007}, volume={16}, pages={1109-1117} }

In this paper, we regard the dilaton in Weyl-scaled induced gravitational theory as a coupled quintessence. Based on this consideration, we investigate the dilaton coupled quintessence (DCQ) model in the ω - ω′ plane, which is defined by the equation of state parameter for the dark energy and its derivative with respect to N (the logarithm of the scale factor a). We find the scalar field equation of motion in the ω - ω′ plane, and show mathematically the properties of attractor solutions which… Expand
