注意力最近已提请对模型中的通货膨胀和精华计划是统一的。在这种“典型的暴胀”模型中，需要一个独特的标量场来扮演暴胀子和后期动力学宇宙学常数的角色。我们在这种情况下解决的问题的初始条件的精髓，并发现，在两个明确的例子中提供，通货膨胀可以唯一地固定他们在允许的范围内，为目前的跟踪。
Attention has been recently drawn towards models in which inflation and quintessence schemes are unified. In such `quintessential inflation' models, a unique scalar field is required to play both the role of the inflaton and of the late-time dynamical cosmological constant. We address the issue of the initial conditions for quintessence in this context and find that, in the two explicit examples provided, inflation can uniquely fix them to be in the allowed range for a present day tracking.
