Abstract: The effects of phase space deformations in standard scalar field cosmology are studied. The deformation is introduced by modifying the symplectic structure of the minisuperspace variables to have a deformed Poisson algebra among the coordinates and the canonical momenta. The resulting theory is knowns as noncomutative cosmology. We show the effects of this deformation in scalar field cosmology and establish a relationship between the noncommutative parameters and Λ.
