我们用统一了三种形式和度规的物体来重新表述玻色十一维超引力的哈密顿形式。对于四维空间的情况，对偶群是明显的，度量和C-场是平等的，即使没有降维是必要的，我们的结果举行。人们也可以用从膜对偶性中出现的广义几何来描述我们的结果。详细描述了扭曲柯朗代数与十一维超引力规范对称性之间的关系。
We reformulate the Hamiltonian form of bosonic eleven dimensional supergravity in terms of an object that unifies the three-form and the metric. For the case of four spatial dimensions, the duality group is manifest and the metric and C-field are on an equal footing even though no dimensional reduction is required for our results to hold. One may also describe our results using the generalized geometry that emerges from membrane duality. The relationship between the twisted Courant algebra and the gauge symmetries of eleven dimensional supergravity are described in detail.
