我们构建了 11 个维度的超重力解,描述了包裹在 Kahler 四循环周围的 D6 膜,其中 B 场沿着膜的 ∞at 方向。该配置与 2+1 维中的 N = 2 非交换规范理论对偶。我们还构造了四个相关的独立的 Killing 旋量。当紧致到IIA型或8d规范超引力时,没有超对称性的超对称现象自然出现。因此,该解决方案还提供了具有四个增压和四种形式的 ∞ux 的 11d 背景,这是从 8d 计量超重力无法获得的。
We construct the supergravity solution in 11 dimensions describing D6-branes wrapped around a Kahler four-cycle with a B-fleld along the ∞at directions of the brane. The conflguration is dual to anN = 2 non-commutative gauge theory in 2+1 dimensions. We also construct the four associated independent Killing spinors. The phenomenon of supersymmetry without supersymmetry appears naturally when compactifying to type-IIA or 8d gauged supergravity. Therefore, this solution also provides an 11d background with four supercharges and four-form ∞ux, which is not obtainable from 8d gauged supergravity.
