多维时空中各向异性度规的研究及由标量场产生附加维

Investigation of anisotropic metric in multidimensional space-time and generation of additional dimensions by scalar field

Sergey V. Yakovlev

摘要:

研究了仅含宇宙项和标量场的高维时空的各向异性度规。证明了标量场的存在等价于多维时空中的各向异性度规,并提出了用标量场产生维数的思想。求解了高维Kazner型时空的Einstein方程,导出了产生额外维的标量场的能量密度表达式,并提出了度规重整化的过程。

英文摘要:

Were investigated anisotropic metric of higher dimensional space-time with only cosmological term and scalar field. Showed, that presence of scalar field is equivalent to anisotropic metric in the multy dimensional space-time and proposed idea of dimensions generation by scalar field. Were solved Einstein's equations for higher dimensional space-time of Kazner's type and derived expressions for density of energy for scalar field, which generate additional dimensions, and proposed the procedure of renormalization of the metric.
