我们证明了最近在AdS5 × S5背景下发现的IIB型超引力无质量引力子多重态标量的四次作用量与规范N = 8的5d超引力对AdS5的作用量的有关部分是一致的.然后利用这个作用量计算N = 4 SYM 4中最低权手征准素算子tr（φ（i φ j））在大N和强t Hooft耦合下的4点函数.
We show that the recently found quartic action for the scalars from the massless graviton multiplet of type IIB supergravity compactified on AdS 5 × S 5 background coincides with the relevant part of the action of the gauged N = 8 5d supergravity on AdS 5 . We then use this action to compute the 4-point function of the lowest weight chiral primary operators tr ( φ ( i φ j ) ) in N = 4 SYM 4 at large N and at strong ‘t Hooft coupling.
