标题： Indeterministic Quantum Gravity V. Dynamics and Arrow of Time

摘要： 本文是论文[gr-qc/9409010, gr-qc/9505034, gr-qc/9603022, gr-qc/9609035]的延续，致力于解开时间箭头起源的谜题。 时间方向的问题归结为过去和未来之间的差异问题。 在确定性动力学和标准非确定性量子理论的动力学中，这一谜题都无法得到解决。 在非确定性量子引力的动力学中，过去可以唯一地被重建，而未来只能在概率层面上进行预测。 因此，过去和未来的问题，以及由此带来的时间方向问题都得到了解决。 显示英文摘要

摘要： This paper is a continuation of the papers [gr-qc/9409010, gr-qc/9505034, gr-qc/9603022, gr-qc/9609035] and is devoted to the riddle of the origin of the arrow of time. The problem of time orientation reduces to that of the difference between the past and the future. The riddle escapes solution in deterministic dynamics and in the dynamics of standard indeterministic quantum theory as well. In the dynamics of indeterministic quantum gravity, the past is reconstructible uniquely, whereas the future may be forecasted only on a probabilistic level. Thus the problems of the past and the future and, by the same token, of time orientation are solved.
