单状态方程两膜世界系统的宇宙学约束

Cosmological constraints for a two brane-world system with single equation of state

Juan L. Perez, Ruben Cordero, L. Arturo Urena-Lopez

摘要:

研究了嵌入在5维时空中的两个3-膜系统,其中第5维在$S^{1}/Z_{2}$轨道上紧化。假设是各向同性的、均匀的和静态的膜,可以证明,当度量系数具有特定的形式时,一个膜的动力学由另一个膜支配。我们研究由此产生的宇宙学时,一个膜是由一个给定的单流体组件占主导地位。

英文摘要:

We present the study of two 3-brane system embedded in a 5-dimensional space-time in which the fifth dimension is compactified on a $S^{1}/Z_{2}$ orbifold. Assuming isotropic, homogeneous, and static branes, it can be shown that the dynamics of one brane is dominated by the other one when the metric coefficients have a particular form. We study the resulting cosmologies when one brane is dominated by a given single-fluid component.
