论文摘要
由宇宙常数的全息自我调整建议的动机，我们概括并研究嵌入较高维度的散装黑洞几何形状中的brane世界的宇宙学。在散装几何形状的平坦，球形和双曲线切片的情况下，我们描述了方程和匹配条件，并找到存在静态溶液的条件。我们解决了在探测器启动中控制动态几何形状的方程式，并详细描述了由此产生的Brane-World宇宙学。特别值得关注的是当bran-world接近黑洞地平线时，溶液的特性。在这种情况下，在勃褐色上诱导的几何形状是de Sitter的几何形状，其熵和温度与较高尺寸散装黑洞的几何形状有关。
Motivated by the holographic self-tuning proposal of the cosmological constant, we generalize and study the cosmology of brane-worlds embedded in a higher-dimensional bulk black hole geometry. We describe the equations and matching conditions in the case of flat, spherical and hyperbolic slicing of the bulk geometry and find the conditions for the existence of a static solution. We solve the equations that govern dynamical geometries in the probe brane limit and we describe in detail the resulting brane-world cosmologies. Of particular interest are the properties of solutions when the brane-world approaches the black hole horizon. In this case the geometry induced on the brane is that of de Sitter, whose entropy and temperature is related to those of the higher dimensional bulk black hole.
