WKB-type Approximation to Noncommutative Quantum Cosmology
arXiv:gr-qc/0701097 · doi:10.1142/S0218271809014376
Abstract
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 is done 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 to cosmology and inflation.
