论文摘要
对于任何基本的量子场理论，单位性，可误算和相对论不变性被认为是必不可少的特性。单位性不可避免地与量子理论的概率解释有关，而术语化的性能保证了其完整性。反过来，相对论不变性是一种对称性，它源自时空的结构。到目前为止，基于度量场的基本局部量子场理论制定基本局部量子场理论的尝试似乎与至少其中一种属性相抵触。在量子ho树的重力中，量子lifshitz的引力理论是特征在于时空之间的各向异性缩放，单位性和可误差性之间的量表，而洛伦兹不变性在高能量下才能牺牲，并且必须仅在低能能下以近似对称性为单位。我回顾了各种扰动量子重力的方法，特别着眼于霍娃重力量化的最新进展，支持其理论地位作为单一，可恢复和紫外线的量子量量子的重力理论。
For any fundamental quantum field theory, unitarity, renormalizability, and relativistic invariance are considered to be essential properties. Unitarity is inevitably connected to the probabilistic interpretation of the quantum theory, while renormalizability guarantees its completeness. Relativistic invariance, in turn, is a symmetry which derives from the structure of spacetime. So far, the perturbative attempt to formulate a fundamental local quantum field theory of gravity based on the metric field seems to be in conflict with at least one of these properties. In quantum Hořava gravity, a quantum Lifshitz field theory of gravity characterized by an anisotropic scaling between space and time, unitarity and renormalizability can be retained while Lorentz invariance is sacrificed at high energies and must emerge only as approximate symmetry at low energies. I review various approaches to perturbative quantum gravity with a particular focus on recent progress in the quantization of Hořava gravity, supporting its theoretical status as a unitary, renormalizable and ultraviolet-complete quantum theory of gravity.
