Inflation in generalized unimodular gravity

he recently suggested generalized unimodular gravity theory, which was originally put forward as a model of dark energy, can serve as a model of cosmological inflation driven by the effective perfect fluid-the dark purely gravitational sector of the theory. Its excitations are scalar gravitons that...
