    • ...That a fundamental scale should exist in the ‘ultimate’ theory of nature seems by now to be fairly well accepted, and it is therefore of interest to examine a program that incorporates such a scale into physics from the outset [28, 29, 31]...
    • ...Despite this, it is by now also well–established that the formal perturbation theory that results from considering such models must have some physical validity, due to the high accuracy of its agreement with experimental results [22, 13]...
    • ...Here we will describe that part of relativistic QG mechanics that is necessary background to consider the evolution of free QG scalar fields in a classical, globally hyperbolic spacetime; further details on interacting quantum fields and gauge fields has appeared elsewhere [31]...
    • ...and are defined in terms of the eight operators [31, Section 4.4] ˜ PA := i∂qA, ˜...
    • ...which is related to the relativistic generalisation of the Heisenberg uncertainty relations [31, Section 3.8]...
    • ...Choosing the normalisation constant ˜ Zl,m as [31]...
    • ...(Note that the difference between the normalisation factors appearing here and those in [31] is due to the fact that we are employing momentum variables exclusively, as opposed to velocity variables.) Renormalising the kernel and taking the l → 0 limit results (in the distributional sense) in the positive frequency Pauli–Jordan function [5, Appendix F] of the Klein–Gordon wave operator [32]...
    • ...Taking the sharp point limit first however, leads to the formal perturbative series of local quantum field theory in any particular model, but only after an infinite renormalisation is performed [31, Section 5.8]...
    • ...Thus agreement of QG field theory models with the remarkably accurate predictions of the formally defined perturbative series of conventional local quantum field theory models [13, 22] is guaranteed at the formal level for small (but non–zero) choice of the fundamental scale l, which one expects on fundamental grounds should be of Planck length order [10]...
    • ...(and indeed may be considered as the local quantum metric in a curved spacetime [29, Section 5.2] [31, Section 4.5])...
    • ...Computing this ‘path integral’ by splitting up the time interval up into N equal pieces [31]: �τ = (τf − τi)/N = τn − τn−1, τi = τ0, τf = τN, τn = τi + n�τ and writing...

    • ...The rectification of this situation is to construct the quantum–geometric propagator [31, Section 4.6] by iterating the propagator (58) over all broken, forward–pointing, geodesic paths between the initial and final points, in analogy with the computation of the transition element in Section 2.2...
    • ...In principle, this should follow from taking the semi-classical limit of quantum–geometric gravitational propagation given in [31, Chapter 8], although it is possible that a study of diffeomorphism invariance of a semi-classical model may shed some light on this issue...
