On the WKB approximation of noncommutative quantum cosmology
Mena,E - Obregón,O - Sabido,M

Formato:	journal article
Enlaces:	In this work we propose a formalism to introduce the effects of noncommutativity to classical cosmological models. The method is based on noncommutative quantum cosmology and by means of a WKB type approximation the noncommutative classical solutions can be obtained.
