Acceleration in Weyl integrable spacetime    [PDF]

John Miritzis

We study homogeneous and isotropic cosmologies in a Weyl spacetime. It is shown that in Weyl integrable spacetime, the corresponding scalar field may act as a phantom field. In this circumstance the Weyl field gives rise to a late accelerated expansion of the Universe for all initial conditions and for a wide range of the parameters.
