论文摘要
本文报告了杨的示意性身份如何转化为纯重力的示意图。为此，我们考虑了爱因斯坦 - 希尔伯特的作用，并遵循卡珀，莱布兰特和梅德拉诺的方法，并扩大了Minkowski公制周围的反向度量密度。与杨理论类似，构建了为重力的取消身份以及幽灵顶点，直到六个价值。
This article reports on how diagrammatic identities of Yang--Mills theory translate to diagrammatics for pure gravity. For this, we consider the Einstein--Hilbert action and follow the approach of Capper, Leibbrandt, and Medrano and expand the inverse metric density around the Minkowski metric. By analogy to Yang--Mills theory, cancellation identities are constructed for the graviton as well as the ghost vertices up to the valency of six.
