论文摘要
我们认为，时间问题不是宇宙进化的量子图片中固有的关键问题。在MinisuperSpace模型的示例中，我们展示了量子演化描述的四种方法，这些方法明确地给出了相似的结果。讨论了这些方法与重力量子理论的相关性。
We argue that the problem of time is not a crucial issue inherent in the quantum picture of the universe evolution. On the minisuperspace model example with the massless scalar field, we demonstrate four approaches to the description of quantum evolution, which give similar results explicitly. The relevance of these approaches to building a quantum theory of gravity is discussed.
