论文摘要
通过考虑以相对论气体的形式，其某些特性非常接近黑体光谱，从而检查了不利条件下通货膨胀率在不利条件下的弹性的可能性。已经证明，这种环境中的初始势能预算被抑制了通货膨胀所需的最低价值。这是我们较早的工作的扩展，我们已经表明，只有从所谓的自我复制阈值上方开始，碰巧的罕见地区就可以主导通货膨胀开始的有利初始条件。
The possibility of the resilience of the beginning of inflation under unfavorable conditions is examined by considering the initial state of the inflaton field to be in the form of a relativistic gas with some of its properties in close proximity to the black body spectrum. It is demonstrated that the initial potential energy budget in such an environment is suppressed beyond the minimal value required for inflation. This is the extension of our earlier work, where we have shown that the rare regions which happen to host favorable initial conditions for the beginning of inflation could come to dominate the late-time Universe only if they started out from above the so-called self-reproduction threshold.
