Generalized unimodular gravity as a form of k-essence
A. O. Barvinsky, N. Kolganov, A. Vikman
We consider modifications of general relativity characterized by a special noncovariant constraint on metric coefficients, which effectively generates a perfect-fluid type of matte…

Dynamics of the generalized unimodular gravity theory
A. O. Barvinsky, N. Kolganov, A. Kurov +1
The Hamiltonian formalism of the generalized unimodular gravity theory, which was recently suggested as a model of dark energy, is shown to be a complicated example of constrained…
