论文摘要
本文提出了引力可观察物的定义及其在ADM叶片框架内的路径积分公式和单型量规类的选择。该方法强制执行BRST不变量规固定，并对移位场进行固定。它产生了已知古典特性的量子水平扩展，即恒定时间叶的内部指标的保形类别定义了重力物理自由度。
This paper proposes a definition of gravitational observables and of their path integral formula within the framework of ADM foliation and the choice of unimodular gauge classes. The method enforces a BRST invariant gauge fixing of the lapse and shift fields. It yields the quantum level extension of the known classical property that the conformal classes of internal metrics of constant Lorentz time leafs define the gravitational physical degrees of freedom.
