Ω-场的暴涨宇宙
Inflation in Ω-Field Cosmology
-
摘要: 本文主旨在应用余提出的Ω-场理论[1],去研究宇宙学问题。假设时空遵从罗伯逊-沃尔克(R-W)度规的结构,而能量张量动量张量只包含Ω-场的项,我们证明宇宙早期存在一急速暴涨阶段。视界问题和平直性问题从而获得简单而自然的解释。Abstract: In thin paper.we shall apply the Ω-field theory as first proposed by Yu[1] to cosmology.Under the assumption that the spacetime geometry of the Universe isdescribed by the Robertson-Walker metric and the matter temsor consists only of the Ω-field,the Universe is found to follow a de Sitter Expansion.The horizon and flatnes sproblems may thus be explained in a simple and natural way.
