摘要:

本文研究了与引力正则耦合的5维标量场系统的含时解。考虑了具有最一般的均匀和各向同性四维度规的时间无关和时间相关的标量场组态。对于与时间无关的标量场,得到了不同空间曲率值$k=0,\pm 1$时标度因子随时间的演化。在含时标量场的情形下,讨论了两类解,并提出了超势形式的一个推广。

英文摘要:

We search for time-dependent solutions for the 5-dimensional system of a scalar field canonically coupled to gravity. Time-independent and time-dependent scalar field configurations with the most general homogeneous and isotropic 4D metric are considered. For the case of time-independent scalar field, the time evolution of the scale factor is obtained for different values of the spatial curvature $k=0,\pm 1$. In the case of time-dependent scalar field, two classes of solutions are discussed and an extension of the superpotential formalism is proposed.
