A Geometric Solution for Dark Energy: Vanishing Dimensions

Open full text 1 citations

Abstract

In this paper, we investigate the possibility that a geometric model of dark energy that assume \textquotedblleft lower dimensions\textquotedblright, could generates a repulsive pressure which cause the current accelerated expansion of the Universe. We show how this geometrical model resemble as quintessence, cosmological constant and phantom energy during the cosmological evolution of the Universe choosing the corresponding matter scale factor as well as the possible consequences of this model in the Universe fate. Finally we perform the dynamical evolution of the model with the other Universe components as well as its domination epoch.
