Abstract
The generalized unimodular theory is revisited and its consequence for cosmology is discussed. The usual matter components of the universe are obtained in a pure geometric way. This result gives a new perspective to the studies of the dark sector of the universe. A background and perturbative analysis is carried out, recovering the corresponding results obtained through the general relativity theory but with a different interpretation.File in questo prodotto:
