论文摘要
我们回顾了量子理论和量子宇宙学基础中的许多问题，特别是在许多世界中的量子力学解释中首选的问题，这种解释与脱碳现象之间的关系，量子宇宙学对量子宇宙学的应用，量子宇宙学的应用，量子宇宙学，量子典型的量化和量化量之间的关系以及众多量之间的关系。我们还讨论了由特殊的微型典型密度矩阵所示的宇宙中根本混合量子状态的概念，其动力学实现是在时空几何和量子物质领域的半经验处理路径积分的形式。这些问题可以被视为H. D. Zeh在七十年代初发表的两篇开创性论文中慷慨地留给我们的科学遗产的一部分。
We review a number of issues in foundations of quantum theory and quantum cosmology including, in particular, the problem of the preferred basis in the many-worlds interpretation of quantum mechanics, the relation between this interpretation and the decoherence phenomenon, application of decoherence approach to quantum cosmology, the relation between the many-worlds interpretation and Anthropic Principle along with the notion of quantum-classical duality. We also discuss the concept of fundamentally mixed quantum state of the Universe represented by a special microcanonical density matrix and its dynamical realization in the form of the semiclassically treated path integral over spacetime geometries and quantum matter fields. These issues can be considered as a part of the scientific legacy of H. D. Zeh generously left to us in his two seminal papers published at the beginning of seventies in Foundations of Physics.
