The “descriptors” ξ A are arbitrary spacetime functions.
Quantum general invariance and loop gravity
If the descriptor ξ 0 vanishes the ξ a represent, for a fixed time, vector fields on the threedimensional spatial manifold.
Quantum general invariance and loop gravity
We now consider the situation when the descriptors ξ 0 do not vanish.
Quantum general invariance and loop gravity
In the former case the descriptors ξ a are invariant; the Lie derivative of ξ a with respect to itself is zero.
Quantum general invariance and loop gravity
This is to be noted for the infinitesmal transformations in (3.11) since substitution of these choices for the descriptors yields δN = ˙N ds and δN a = ˙N ads.
Quantum general invariance and loop gravity

Nonlocality and information flow: The approach of Deutsch and Hayden
We can do more than merely note that the descriptors of a set of interacting systems do not depend on unitary operations on a disjoint set, however.
Nonlocality and information flow: The approach of Deutsch and Hayden
In fact we can see that the descriptor at time t of a given system will depend, apart from the history of operations applied to it alone, only on its previous interactions and on the histories and past interactions of the systems it has interacted with.
Nonlocality and information flow: The approach of Deutsch and Hayden
Figure 1: a) At t = 1, a unitary operation, U1 , which acts only on system j is applied; the descriptor of system i, qi (1), is unaffected.
Nonlocality and information flow: The approach of Deutsch and Hayden
To re-emphasize that the Deutsch-Hayden descriptor of a system at time t will not, however, depend on what happens at t to a system with which it has interacted in the past, we take the following simple example (Fig 1).
Nonlocality and information flow: The approach of Deutsch and Hayden
Immediately following the measurement, the descriptor of system 1 will depend on θ, but not on the parameter characterizing the distant measurement, φ.
