摘要:

研究了具有类Higgs势和负宇宙学常数的非最小耦合标量场宇宙学模型的动力学。在这些模型中,宇宙演化的暴胀阶段变成了宇宙演化的准周期阶段,哈勃参数从正值到负值的振荡行为。根据初始条件,哈勃参数可以执行一个或几个周期,然后永远变为负值。

英文摘要:

We study dynamics of non-minimally coupled scalar field cosmological models with Higgs-like potentials and a negative cosmological constant. In these models the inflationary stage of the Universe evolution changes into a quasi-cyclic stage of the Universe evolution with oscillation behaviour of the Hubble parameter from positive to negative values. Depending on the initial conditions the Hubble parameter can perform either one or several cycles before to become negative forever.
