Oral comunication

Abstract
In this talk, we present some extensions of unimodular gravity, where actions beyond Hilbert-Einstein action are considered. From the classical point of view, the unimodular versions of such extensions are completely equivalent to their originals, but an effective cosmological constant arises naturally. Conformal transformations and cosmological solutions are analyzed within this framwework.
