论文摘要
我们将天体领域的软$ s $ matrices重新塑造为某些$ 2 $维拓扑缺陷的相关函数。为了指出软光子和软重力案例之间的双复制结构，我们在相应的拓扑模型和量规不变性的重新启动之间获得了推定的经典双复制，而等价原理是$ 2 $维理论的病房身份。
We recast the soft $S$-matrices on the celestial sphere as correlation functions of certain $2$-dimensional models of topological defects. In pointing out the double copy structure between the soft photon and soft graviton cases, we arrive at a putative classical double copy between the corresponding topological models and a rederivation of gauge invariance and the equivalence principle as Ward identities of the $2$-dimensional theories.
