AbstractAbstract
[en] Recently Moffat showed that the Szafron inhomogeneous cosmological solution can lead to an accelerating in stationary period without a large initial vacuum energy and with Λ = 0 in the early universe near the Planck time, combined with an accelerating universe at late times, in the nonlinear regime with galaxy structure and voids, without need to introduce negative pressures or a cosmological constant. Here we present an inhomogeneous and anisotropic cosmological model, in 2+1 gravity, which satisfy all the energy conditions, although it generates an accelerated universe. We work in a 2+1 gravity scenario in order to simplify the equations system and to allow us to find analytical and simple solutions. Our propose is basically to improve our understanding on the role of inhomogeneities on the acceleration of the universe. (author)
