摘要:

在本文中,我们重新审视Einstein-Friedman方程和Abel方程之间的关系,以证明如何将其应用于充满实值标量场的平坦Friedman宇宙中的暴胀分析。分析进行了三个不同的情况下,多项式的潜力。通过对Abel方程的数值积分,给出了相对于场的初值,慢滚动和暴胀都成立的充要条件.此外,还确定了慢滚动条件与通货膨胀之间的关系。

英文摘要:

In this paper we revisit the relationship between the Einstein--Friedman and the Abel equations to demonstrate how it might be applied to the inflationary analysis in a flat Friedman universe filled with a real-valued scalar field. The analysis is performed for three distinct cases of polynomial potentials. As a result of a numeric integration of Abel equation, the necessary and sufficient conditions for both slow-rolling and inflation proper are estimated with respect to the initial value of the field. In addition, the relationship between the slow-rolling condition and the inflation is ascertained.
