BF gravity and the Immirzi parameter
Open accessAbstract
We propose a novel BF-type formulation of real four-dimensional gravity, which generalizes previous models. In particular, it allows for an arbitrary Immirzi parameter. We also construct the analogue of the Urbantke metric for this model.

Generalized matrix models probably offer a path to include matter, because coupling of matter fields to gravity was already studied in two-dimensional matrix models [109,115,116].
“The construction of the generalized matrix models gives probably a path to follow in this direction, since the coupling of matter fields to gravity was already studied in the context of two-dimensional matrix models [109,115,116].”

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.
