我们展示了如何通过严格的因式分解来构造由三点振幅定义的扩展引力理论的矩阵。结果矩阵的树幅服从与爱因斯坦引力相同的软奇点定理，包括次、次主导项。
We show how theS-matrix of an extended theory of gravity defined by its three-point amplitudes can be constructed by demanding factorisation. The resultantS-matrix has tree amplitudes obeying the same soft singularity theorems as Einstein gravity including the sub-sub-leading terms.
