Abstract: A comprehensive theory of the Weyl-Wigner formalism for the canonical pair angles-angular momentum is presented, with special emphasis in the implications of rotational periodicity and angularmomentum discreteness.

Sabido, M.",,"2009",,"In this paper, we develop and apply the WKB-type approximation to several examples of noncommutative quantum cosmology, obtaining the time evolution of the noncommutative universe. This is accomplished by starting from a noncommutative quantum formulation of cosmology, where the noncommutativity is introduced by a deformation on the minisuperspace variables. This procedure gives a straightforward algorithm to incorporate noncommutativity into cosmology and inflation. " 2009 World Scientific Publishing Company.
