Abstract

Abstract We consider the possibility of the influences of additional dimensions on the dynamics of the expansion of our Universe. It is shown that this influence is expressed only through the anisotropy parameter of additional dimensions. In the isotropic (in relation to additional dimensions) case the dynamics of our world remains constant. All calculations were carried out for a single-component ideal fluid with power diagonal metrics. The dynamic characteristics of the scale factor have allowed us to draw a conclusion about the physical nature of the initial substance.

附加维度对宇宙膨胀动力学的影响

我们考虑额外维度对我们宇宙膨胀动力学影响的可能性。结果表明，这种影响仅通过附加维度的各向异性参数来表示。在各向同性(相对于附加维度)的情况下，我们世界的动力学保持不变。所有的计算都是针对具有功率对角线指标的单组分理想流体进行的。比例因子的动态特性使我们能够得出关于初始物质的物理性质的结论。
