论文摘要
在这里，我们考虑将天体的codimension-1切片以一种尊重我们用$ \ Mathcal {i}^\ pm $的零发电机来鉴定的能力的方式将天体的codimension-1切片升至散装时空的codimension-1切片。天体对称性的2D电流的轮廓积分将量规理论和天室身份的2型发电机的标准边界积分提升到Noether定理。
Here we consider what happens when we lift a codimension-1 slice of the celestial sphere to a codimension-1 slice of the bulk spacetime in a manner that respects our ability to quotient by the null generators of $\mathcal{I}^\pm$ to get to our codimension-2 hologram. The contour integrals of the 2D currents for the celestial symmetries lift to the standard boundary integrals of the 2-form generators for the gauge theory and celestial Ward identities follow directly from Noether's theorem.
