论文摘要
我们得出了一种扰动公式，用于两种四维几何形状之间的直接相互作用。根据光谱作用原则，我们给出了明确的电位，直至平坦真空周围的三阶扰动。我们将相互作用的主要术语表示为两个指标的多项式，并将扩展与双光重力模型进行比较。
We derive a perturbative formula for the direct interaction between two four-dimensional geometries. Based on the spectral action principle we give an explicit potential up to the third order perturbation around the flat vacua. We present the leading terms of the interaction as polynomials of the invariants of the two metrics and compare the expansion to the models of bimetric gravity.
