Noncommutative Conformally Coupled Scalar Field Cosmology and its Commutative Counterpart
G. D. Barbosa
We study the implications of a noncommutative geometry of the minisuperspace variables for the FRW universe with a conformally coupled scalar field. The investigation is carried ou…

Noncommutative Geometry and Cosmology
G. D. Barbosa, N. Pinto-Neto
We study some consequences of noncommutativity to homogeneous cosmologies by introducing a deformation of the commutation relation between the minisuperspace variables. The investi…
