德西特狭义相对论:对宇宙学的影响

De Sitter Special Relativity: Effects on Cosmology

R. Aldrovandi, J. G. Pereira

摘要:

本文考察了德西特狭义相对论对物理宇宙学标准宇宙模型的主要推论。在这个理论中,宇宙学常数λ表现为适当的共形流,它必须加到通常的能量-动量密度上。由于保形电流本身在没有源的情况下会消失,因此λ最终取决于物质的含量,并且原则上可以计算。通过简单而合理的近似,得到了一个非常接近于交叉超新星/BBR数据的现代值。还发现了一个多项式型的原始膨胀,并对通常的同动观测器的概念作了一些修改。

英文摘要:

The main consequences of de Sitter Special Relativity to the Standard Cosmological Model of Physical Cosmology are examined. The cosmological constant Lambda appears, in this theory, as a manifestation of the proper conformal current, which must be added to the usual energy-momentum density. As that conformal current itself vanishes in absence of sources, Lambda is ultimately dependent on the matter content, and can in principle be calculated. A present-day value very close to that given by the crossed supernova/BBR data is obtained through simple and reasonable approximations. Also a primeval inflation of polynomial type is found, and the usual notion of co-moving observer is slightly modified.
