论文摘要
我们考虑了通过将韦森的诱发物质方法应用于5D广义的Brans-Dicke理论，以四个维度考虑了Brans-Dicke理论（MBDT）的修改版本。在5D中，模型由纯真空组成，除标量场外，没有自我相互作用的潜力。将5D几何形状限制为Kasner最初研究的各向异性Bianchi I型宇宙模型的概括，我们得出了诱导的能量摩尔植物。我们通过如此诱发的不完美流体讨论了MBDT中的能量条件及其边界，以关注当今宇宙的现实模型，并考虑该空间均匀和各向异性模型的大规模行为。我们讨论在MBDT背景下如何满足或违反能源条件，目的是在当前时代提供可行的宇宙描述。
We consider a modified version of Brans-Dicke theory (MBDT) in four dimensions obtained by applying the induced matter method of Wesson to a 5D generalized Brans-Dicke theory. In 5D the model consists of pure vacuum, with no self-interacting potential, except for a scalar field. Constraining the 5D geometry to be a generalization of the anisotropic Bianchi type I universe model first studied by Kasner, we derive the induced energy-momentum. We discuss the energy conditions and their bounds in the MBDT with such an induced imperfect fluid, with an eye toward a realistic model of the present-day universe, and consider the large-scale behavior of that spatially homogeneous and anisotropic model. We discuss how the energy conditions would be satisfied or violated in the context of MBDT, with the aim of providing a feasible description of the universe in the current era.
