论文摘要
穿着的金属方法表明，通过证明它无法实现正确的无限无限关系，从而违反了一般的协方差。主要的基本原因 - 与协方差不相容的背景自由度和不均匀模式的分离 - 与其他方法（例如混合环量子宇宙学）共享。
The dressed-metric approach is shown to violate general covariance by demonstrating that it cannot have an off-shell completion in which the correct infinitesimal relations of space-time hypersurface deformations are realized. The main underlying reason -- a separation of background degrees of freedom and modes of inhomogeneity that is incompatible with covariance -- is shared with other approaches such as hybrid loop quantum cosmology.
