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.

  1. Nontrivial constitutive laws and unified structures in constrained BF theory

    hep-th 2025-04 conditional novelty 5.0 of 10

    Changing the gravitational constitutive law in BF theory does not force any change in the internal gauge-theory constitutive law, because no canonical map connects the two sectors.

  2. Les Houches lectures on Spinfoam Path Integrals

    gr-qc 2026-07 accept novelty 2.0 of 10

    A pedagogical review of spinfoam path integrals, from 1d quantum mechanics and 2d BF theory through Ponzano-Regge/Turaev-Viro to the 4d EPRL model, accurate but with no new results.
