论文摘要
我们在自动划分领域的Yang-Mills和重力工作，我们向径向扩展中的所有阶构建了如何在Null Infinity构建扩展相位空间。这将这些理论的红外行为的对称起源形式化为所有子领先顺序。作为推论，我们还从YM量规变换子集中到了转换参数中所有订单的一部分，从YM量规变换的子集进行了双复制映射，据我们所知，这在文献中尚未提出。
Working in the self-dual sector for Yang-Mills and gravity, we show how to construct an extended phase space at null infinity, to all orders in the radial expansion. This formalises the symmetry origin of the infrared behaviour of these theories to all sub-leading orders. As a corollary, we also derive a double copy mapping from a subset of YM gauge transformations to a subset of diffeomorphisms to all orders in the transformation parameters, which to our knowledge has not been presented before in the literature.
