Definition of reference system in the context of General Relativity [closed]
I'm in trouble with the definition of reference system in the context of General Relativity intended as coordinate chart (i.e. no frame field).
Various sources define it as a one-to-one smooth mapping ...

Does quantum non-commutativity constrain the Tomita-Takesaki modular flow to be one-dimensional for physically realizable observer states?
The Tomita-Takesaki theorem, applied to a faithful normal state $ρ$ on a von Neumann algebra, always produces a one-parameter automorphism group — mathematically, this is built into the theorem. My ...

In algebraic QFT, since uncertainty is ontic, should the reference state be a band rather than a sharp KMS state?
In type-III$_{1}$ algebraic QFT, since the uncertainty principle is ontic, shouldn't the reference state be a band rather than a sharp KMS state, and would this cure UV divergences naturally?
In ...
