Canonical structure and extra mode of generalized unimodular gravity

Canonical structure and extra mode of generalized unimodular gravity
Markku Oksanen, Rodrigo Bufalo
We consider a recently proposed generalization of unimodular gravity, where the lapse function is constrained to be equal to a function of the determinant of the spatial metric $f(h)$, as a potential origin of a dark fluid with a generally $h$-dependent equation of state parameter. We establish the ...
