5D中空Kaluza-Klein解的现代宇宙学

Modern cosmologies from empty Kaluza-Klein solutions in 5D

J. Ponce de Leon

摘要:

我们证明了Davidson-Sonnenschtein-Vozmediano,{ \em Phys. Rev.} { \bf D32}(1985)1330,在“旧”卡鲁扎-克莱因引力中,在适当的解释下,可以产生大量的4D宇宙学模型,其中包括对广义相对论的高维修正,这些修正是由非紧化5D引力的“现代”版本预测的,例如,诱导物质和膜世界理论。这是第一次以系统的方式研究这些解决方案作为4D宇宙学模型的嵌入。它们提供了一种不同的表述,这是对当前版本的5D相对论中使用的方法的补充。

英文摘要:

We show that the empty five-dimensional solutions of Davidson-Sonnenschtein-Vozmediano, {\em Phys. Rev.} {\bf D32} (1985)1330, in the "old" Kaluza-Klein gravity, under appropriate interpretation can generate an ample variety of cosmological models in 4D, which include the higher-dimensional modifications to general relativity predicted by "modern" versions of noncompactified 5D gravity as, e.g., induced-matter and braneworld theories. This is the first time that these solutions are investigated in a systematic way as embeddings for cosmological models in 4D. They provide a different formulation, which is complementary to the approaches used in current versions of 5D relativity.
