Late time acceleration in a deformed phase space model of dilaton cosmology
arXiv:1003.1194 · doi:10.1016/j.physletb.2010.03.016
Abstract
The effects of noncommutativity on the phase space of a dilatonic cosmological model is investigated. The existence of such noncommutativity results in a deformed Poisson algebra between the minisuperspace variables and their momenta conjugate. For an exponential dilaton potential, the exact solutions in the commutative and noncommutative cases, are presented and compared. We use these solutions to address the late time acceleration issue of cosmic evolution.
