Noncommutativity and scalar field cosmology
Physical Review D—Particles, Fields, Gravitation, and Cosmology, 2007•APS
In this work we extend and apply a previous proposal to study noncommutative cosmology
to the Friedmann-Robertson-Walker cosmological background coupled to a scalar field. This
is done in classical and quantum scenarios. In both cases noncommutativity is introduced in
the gravitational field as well as in the scalar field through a deformation of minisuperspace,
and we are able to find exact solutions. Finally, the effects of noncommutativity on the
classical evolution are analyzed.
