Is noncommutativity related with the smallness of ?
E. Mena, O. Obregón, M. Sabido
In this letter we study the effects of a noncommutative minisuperspace, including matter degrees of freedom on a FRW universe with cosmological constant. In this setting the vacuum…

(Non)commutative isotropization in Bianchi I with Barotropic perfect fluid and Cosmological
C. Ortiz, E. Mena-Barboza, M. Sabido +1
We present the classical solutions to the Einstein field equations derived using the WKB-like and Hamilton procedures. The investigation is carried out in the commutative and nonco…

WKB-type Approximation to Noncommutative Quantum Cosmology
E. Mena, O. Obregon, M. Sabido
In this work, we develop and apply the WKB approximation to several examples of noncommutative quantum cosmology, obtaining the time evolution of the noncommutative universe, this…
