标准宇宙学模式方程在快速振荡下的平均化:宇宙学项对有效正压系数平均值的影响

Averaging of the Equations of the Standard Cosmological Model over Rapid Oscillations: Influence of the cosmological term on the mean value of the effective barotropic coefficient

Yurii Ignat'ev, A. R. Samigullina

摘要:

借助于作者编写的应用软件包,我们对经典标量场的有效总正压系数($κ=(-λ+ p)/(λ+ε$)和宇宙学项进行了平均,并证明了在宇宙学演化过程中,当宇宙学常数足够大时,宇宙从暴胀阶段过渡到非相对论阶段,然后经过一个平台期,它会过渡到一个较晚的通货膨胀阶段。

英文摘要:

With the help of an applied software package written by the authors, we have averaged the effective total barotropic coefficient $κ=(-λ+ p)/(λ+ε$) of the classical scalar field and the cosmological term and have shown that during cosmological evolution for sufficiently large values of the cosmological constant the Universe transitions from the inflationary stage to a nonrelativistic stage, and then, after a plateau, it transitions to a later inflationary stage.
