具有曲率效应的膜中的晚时加速度

Late-time acceleration in a brane with curvature effects

Mariam Bouhmadi-Lopez, Paulo Vargas Moniz

摘要:

在本文中,我们研究了在LDGP模型中的幻影状制度,可以扩大包括一个高斯-邦纳(GB)项到散装。然而,我们发现,相反的情况发生:GB效应似乎反而引起故障的幻影般的行为在一个更小的红移。

英文摘要:

In this paper we investigate if the phantom-like regime in the LDGP model can be enlarged by the inclusion of a Gauss-Bonnet (GB) term into the bulk. However, we show that the opposite occurs: the GB effect seems instead to induce a breakdown of the phantom-like behaviour at an even smaller redshift.
