Abstract

We provide a simple proof of the topological invariance of the Turaev–Viro model (corresponding to simplicial 3D pure Euclidean gravity with cosmological constant) by means of a novel diagrammatic formulation of the state sum models for quantum BF theories. Moreover, we prove the invariance under more general conditions allowing the state sum to be defined on arbitrary cellular decompositions of the underlying manifold. Invariance is governed by a set of identities corresponding to local gluing and rearrangement of cells in the complex. Due to the fully algebraic nature of these identities our results extend to a vast class of quantum groups. The techniques introduced here could be relevant for investigating the scaling properties of non-topological state sums, proposed as models of quantum gravity in 4D, under refinement of the cellular decomposition.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • BF amplitudes are independent of the regulating triangulation, and with suitable regularization of bubble divergences the BF partition function is topologically invariant and discretization independent.

    “using this graphical notation one can easily prove the discretization independence of the BF amplitudes.”

  • Equation (248) has been proven for simplicial decompositions, and its generalization to arbitrary cellular decomposition was obtained.

    “Eq. (248) has been proven in this case for the case of simplicial decompositions in [364]; see also [363, 238]. The generalization for arbitrary cellular decomposition was obtained in [206].”

  • The amplitudes of this spin-foam model are independent of the chosen cellular decomposition.

    “The crucial property of this spin-foam model is that the amplitudes are independent of the chosen cellular decomposition [363, 206].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
