由Granda和Oliveros的工作激励[L.Granda,A.Oliveros,Phys.让我们来吧。B 671(2009)199],我们将他们的工作推广到非平坦情形。在非平坦的FRW宇宙中,我们用新的全息暗能量模型研究了经典、快子、K本质和膨胀子标量场模型之间的对应关系。我们重建了这些标量场模型的势和动力学,它们描述了宇宙的加速膨胀。在平坦宇宙的极限情况下,即k=0,[L.Granda,A.Oliveros,Phys.让我们来吧。B671(2009)199]。
Motivated by the work of Granda and Oliveros [L.N. Granda, A. Oliveros, Phys. Lett. B 671 (2009) 199], we generalize their work to the non-flat case. We study the correspondence between the quintessence, tachyon, K-essence and dilaton scalar field models with the new holographic dark energy model in the non-flat FRW universe. We reconstruct the potentials and the dynamics for these scalar field models, which describe accelerated expansion of the universe. In the limiting case of a flat universe, i.e. k=0, all results given in [L.N. Granda, A. Oliveros, Phys. Lett. B 671 (2009) 199] are obtained.
