Path integral measures and diffeomorphism invariance

Abstract Much like the action, diffeomorphism invariance can be used to fix the form of the path integral measure in quantum gravity. Moreover, since there is a redundancy between what constitutes “the action” and what constitutes “the measure” one can always pick a minimal form of the latter. Howev...
