摘要
In the present work we show that the widely believed pathology of the nonunitarity of anisotropic quantum cosmological models cannot be a generic problem. We exhibit a nontrivial example, a Bianchi-I model with an ultrarelativistic fluid, that has a well-behaved time independent norm. We also show that a suitable operator ordering should produce time independent norms for the wave packets in the case of other more realistic fluids as well.
