| 英文摘要 | We show that the most general dark energy model that possesses a scaling solution rho phi alpha a(n) is the k-essence model, which includes both of the quintessence and tachyon models. The exact scaling solutions are then derived. The potential that gives the tracking solution in which dark energy exactly tracks the background matter field is the inverse squared potential. The quintessence field with exponential potential can be obtained from the k-essence field with the inverse squared potential. We also find the fixed points and study their main properties, whereby the scalar field dominant fixed point is identified. (c) 2006 Elsevier B.V. All rights reserved. |
