论文摘要
（典型）量子重力中的物理学需要明显具有差异性不变。因此，需要根据明显的差异性不变算子来制定物理可观察物，这必然是复合的。这使得一般涉及评估，即使量子重力的具体实施通常应触及式（半）。 Fröhlich，Morchio和Strocchi开发的用于平面时间量子场理论的机制也可能适用于这种情况。可以通过动态三角测量等方法测试这种机制。
Physics in (canonical) quantum gravity needs to be manifestly diffeomorphism-invariant. Consequently, physical observables need to be formulated in terms of manifestly diffeomorphism-invariant operators, which are necessarily composite. This makes an evaluation in general involved, even if the concrete implementation of quantum gravity should be treatable (semi-)perturbatively in general. A mechanism developed by Fröhlich, Morchio and Strocchi for flat-space-time quantum field theory may also be applicable in this case. It may be possible to test this mechanism with methods like dynamical triangulation.
