Abstract
A Kantowski-Sachs model with a modified quantization prescription is considered. Such quantization rules, inspired by the so-called generalized uncertainty principle, correspond to a modified commutation relation between minisuperspace variables and their conjugate momenta. For a wide range of the modification parameter, this approach differentiates from the standard results by the presence of a potential well in the corresponding Wheeler-DeWitt equation. This then produces the appearance of a set of wave functions, with corresponding discrete energy spectrum.File in questo prodotto:
