We present a constructive derivation of all four-point tree-level holographic correlators for eleven dimensional supergravity on ${\mathrm{AdS}}_7\times S^4$. These correlators correspond to four-point functions of arbitrary one-half BPS operators in the six-dimensional (2,0) theory at large central charge. The crucial observation is that the polar part of the correlators in Mellin space is fully captured by a drastically simpler maximally $R$-symmetry violating amplitude, while the contact part is fully fixed by superconformal Ward identities and the flat space limit.

AdS7×S4上用于M理论的所有树级关联器

我们提出了关于11维超重力的所有四点树级全息相关器的建设性推导 ${\mathrm{广告}}_7\times {\mathrm{小号}}^4$。这些相关器对应于大中心电荷的六维（2,0）理论中任意二分之一BPS算符的四点函数。关键的观察结果是，梅林空间中相关器的极点部分被极大简化的最大值完全捕获了$\mathrm{[R}$-对称性超出幅度，而接触部分则通过超共形Ward身份和平坦空间限制完全固定。
