我们讨论了六维流形M上的十一维超引力的一致截断，在五维空间中保持最小= 2的超对称性。这些是基于M上广义E6（6）切丛的G-S-USp（6）结构，使得内禀挠率是一个常数G-S单态.我们详细说明了定义完整玻色子截断的算法，然后将这种形式主义应用于包含由包裹在黎曼曲面上的M5-膜产生的扭曲AdS 5× w M解的一致截断。与Maldacena-Nuñez的= 2解相关的广义U（1）结构导致了具有四个矢量多重态、一个超多重态和SO（3）× U（1）× S规范群的五维超引力。与“BBBW”解决方案的广义结构产生两个矢量多重峰，一个超多重峰和阿贝尔规范。我们认为，这些是最普遍的一致截断在这样的背景。
We discuss consistent truncations of eleven-dimensional supergravity on a six-dimensional manifold M, preserving minimal= 2 supersymmetry in five dimensions. These are based on G S⊆ USp (6) structures for the generalised E 6 (6) tangent bundle on M, such that the intrinsic torsion is a constant G S singlet. We spell out the algorithm defining the full bosonic truncation ansatz and then apply this formalism to consistent truncations that contain warped AdS 5× w M solutions arising from M5-branes wrapped on a Riemann surface. The generalised U (1) structure associated with the= 2 solution of Maldacena-Nuñez leads to five-dimensional supergravity with four vector multiplets, one hypermultiplet and SO (3)× U (1)× ℝ gauge group. The generalised structure associated with “BBBW” solutions yields two vector multiplets, one hypermultiplet and an abelian gauging. We argue that these are the most general consistent truncations on such backgrounds.
