标题： Time in Quantum Geometrodynamics

摘要： 我们重新审视量子几何动力学中的时间问题，并提出在真正动态变量空间上的量子化过程。 该过程将量子化问题与由普遍协变对称性引起的约束强制分离开来。 该理论的结果不同于标准方法，它考虑了相对于约束处于非壳状态的态，从而避免了时间的问题。 在这种方法中，量子几何动力学、普遍协变性和时间的解释作为几何动力学演化总问题的解决方案的一部分共同出现。 显示英文摘要

摘要： We revisit the issue of time in quantum geometrodynamics and suggest a quantization procedure on the space of true dynamic variables. This procedure separates the issue of quantization from enforcing the constraints caused by the general covariance symmetries. The resulting theory, unlike the standard approach, takes into account the states that are off shell with respect to the constraints, and thus avoids the problems of time. In this approach, quantum geometrodynamics, general covariance, and the interpretation of time emerge together as parts of the solution of the total problem of geometrodynamic evolution.
