论文摘要
遵循在整个相空间中双重重力模型的哈密顿结构，我们构建了差异量规对称性的生成功能。正如预期的那样，该发电机是由系统的一级约束构建的。我们表明，该规格发生器可以很好地提供规范变量的量规变换。
Following the Hamiltonian structure of bi-gravity and multi-gravity models in the full phase space, we have constructed the generating functional of diffeomorphism gauge symmetry. As is expected, this generator is constructed from the first class constraints of the system. We show that this gauge generator works well in giving the gauge transformations of the canonical variables.
