本文研究了一个带有Gauss-Bonnet相互作用项的Randall-Sundrum模型。我们特别考虑了膜上的弗里德曼-罗伯逊-步行者度规，并分析了由此产生的宇宙学情景。它表明，通常的弗里德曼方程恢复膜上。能量密度与压力之间的状态方程由匹配条件唯一确定。发现了一个具有负压的宇宙学解。
We study a Randall-Sundrum model modified by a Gauss-Bonnet interaction term. We consider, in particular, a Friedmann-Robertson-Walker metric on the brane and analyze the resulting cosmological scenario. It is shown that the usual Friedmann equations are recovered on the brane. The equation of state relating the energy density and the pressure is uniquely determined by the matching conditions. A cosmological solution with negative pressure is found.
