在7维内部黎曼空间上，我们给出了一个新的相容截断，将D= 11的超引力截断为D= 4= 2的最小规范超引力，对应于最一般的一类具有AdS 4因子和= 2超对称的D= 11解.提出了一个截断的假设，并在D= 11的比安奇恒等式、玻色子运动方程和引力子的超对称变化的水平上检验了它的一致性。一般类包括一个= 2 AdS 4的解决方案对偶的共形，低能量的物理相对应的质量变形的M2膜场理论。一个一致的截断最近构建在这个特定的几何恢复从我们的形式主义。
We present a new consistent truncation of D= 11 supergravity to D= 4= 2 minimal gauged supergravity, on the seven-dimensional internal Riemannian space corresponding to the most general class of D= 11 solutions with an AdS4 factor and= 2 supersymmetry. A truncation ansatz is proposed and its consistency checked at the level of the D= 11 Bianchi identity, bosonic equations of motion, and supersymmetry variations of the gravitino. The general class includes an= 2 AdS 4 solution dual to the conformal, low-energy physics phase corresponding to a mass deformation of the M2-brane field theory. A consistent truncation recently constructed on this particular geometry is recovered from our formalism.
