A结构我们推导出了对应于四维最大规范超引力上升的D = 11超引力的4形式场强的新解答。特别是,ansätze直接给出了四维最大规范超引力标量和矢量形式的4-形式场强分量--以这种方式,它们提供了D = 11超引力的所有四维一致截断的明确提升。新的ansätze提供了一个大大简单的方法,为提升d = 4流动相比,以前可用的方法,使用3-形式和6-形式的潜在ansätze。Freund-Rubin项的解析式使我们可以根据d = 4规范超引力的标量势及其一阶导数来推测后者的“主公式”。我们还解决了一个长期存在的难题,从隆升ansätze获得的流量的反对称。
A bstractWe derive new ansätze for the 4-form field strength of D = 11 supergravity corresponding to uplifts of four-dimensional maximal gauged supergravity. In particular, the ansätze directly yield the components of the 4-form field strength in terms of the scalars and vectors of the four-dimensional maximal gauged supergravity — in this way they provide an explicit uplift of all four-dimensional consistent truncations of D = 11 supergravity. The new ansätze provide a substantially simpler method for uplifting d = 4 flows compared to the previously available method using the 3-form and 6-form potential ansätze. The ansatz for the Freund-Rubin term allows us to conjecture a ‘master formula’ for the latter in terms of the scalar potential of d = 4 gauged supergravity and its first derivative. We also resolve a long-standing puzzle concerning the antisymmetry of the flux obtained from uplift ansätze.
