论文摘要
当前对量子重力（QG）重新归一化的理解是基于以下事实：协变量QG模型中有效作用的紫外线差异是协变量的局部表达式。这种基本陈述在QG中起着核心作用，因此，重要的是要以QG理论的最广泛范围来证明它。使用Batalin-Vilkovisky技术和背景场方法，我们为量子重强度的通用模型详细说明了量规不变性的证明，该模型是差异不变的，并且没有其他可能的，可能是异常的，对称性的。
The current understanding of renormalization in quantum gravity (QG) is based on the fact that UV divergences of effective actions in the covariant QG models are covariant local expressions. This fundamental statement plays a central role in QG and, therefore, it is important to prove it for the widest possible range of the QG theories. Using the Batalin-Vilkovisky technique and the background field method, we elaborate the proof of gauge invariant renormalizability for a generic model of quantum gravity that is diffeomorphism invariant and does not have additional, potentially anomalous, symmetries.
