Nonperturbative summation over 3D discrete topologies

Abstract

The group field theories realizing the sum over all triangulations of all topologies of 3D discrete gravity amplitudes are known to be nonuniquely Borel summable. We modify these models to construct a new group field theory which is proved to be uniquely Borel summable, defining in an unambiguous way a nonperturbative sum over topologies in the context of 3D dynamical triangulations and spin foam models. Moreover, we give some arguments to support the fact that, despite our modification, this new model is similar to the original one, and therefore could be taken as a definition of the sum over topologies of 3D quantum gravity amplitudes.

  • Recent work has suggested a method for summing over all topologies in spin foam models, allowing quantum fluctuations of spacetime topology.

    “While spin foam models ordinarily assume a fixed spacetime topology, recent work has suggested a method for summing over all topologies as well, thus allowing quantum fluctuations of spacetime topology [132].”
  • Freidel and Loupre considered a variant of the Ponzano-Regge model and showed that although the sum over topologies diverges, it is Borel summable.

    “Building on work by Boulatov [60], Freidel and Loupre have recently considered a variant of the Ponzano-Regge model, and have shown that although the sum over topologies diverges, it is Borel summable [132].”
  • The model considered by Freidel and Loupre is not exactly the Ponzano-Regge model, and it is not clear that it is ordinary quantum gravity.

    “The model considered in [132] is not exactly the Ponzano-Regge model, and it is not clear that it is really “ordinary” quantum gravity.”
  • Freidel and Louapre demonstrated that such re-summing is possible for some three-dimensional group field theories.

    “Freidel and Louapre [187] have shown that this is indeed possible for certain GFT’s in three dimensions.”

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.
