论文摘要
通过执行哈密顿分析和规范变换，获得了4维时空上的5维Kaluza-Klein理论的连接动力学。在该理论的球形对称模型中实现了脱刀片化，而没有引入5维重力以外的其他物质领域。因此，可以通过较高维度时空的几何自由度来提供物理时间演化和物理空间坐标。
The connection dynamics of the 5-dimensional Kaluza-Klein theory reduced on 4-dimensional spacetime is obtained by performing the Hamiltonian analysis and canonical transformations. Deparametrization is achieved in the spherically symmetric model of the theory without introducing additional matter fields beyond the 5-dimensional gravity. Thus the physical time evolution and the physical spatial coordinate can be provided by the geometrical degrees of freedom in the higher dimensional spacetime.
