This short note is devoted to the Hamiltonian analysis of the Unimodular Gravity.We treat the unimodular gravity as General Relativity action with the unimodular constraint imposed with the help of Lagrange multiplier. We perform the canonical analysis of the resulting theory and determine its constraint structure.

  1. Canonical analysis of unimodular Pleba\'nski gravity

    gr-qc 2024-11 accept novelty 6.0 of 10

    A canonical analysis of unimodular Plebański gravity shows that the Hamiltonian density is constrained only to be constant, promoting the cosmological constant to an integration constant.

  2. Unimodular quantum cosmology in the connection representation: A minimal model

    gr-qc 2026-02 conditional novelty 5.0 of 10

    In a flat, empty unimodular quantum cosmology in connection variables, positive-cosmological-constant wave functions vanish at zero volume, while a negative cosmological constant is excluded by operator regularity and...
