Examination of the nature of the Bianchi type cosmological singularities
Piotr Dzierzak
We present quantum (and classical) Bianchi I model, with free massless scalar field, of the Universe. Our model may be treated as the simplest prototype of the quantum BKL (Belinsk…

Bianchi I model in terms of nonstandard loop quantum cosmology: Quantum dynamics
Przemyslaw Malkiewicz, Wlodzimierz Piechocki, Piotr Dzierzak
We analyze the quantum Bianchi I model in the setting of the nonstandard loop quantum cosmology. Elementary observables are used to quantize the volume operator. The spectrum of th…

Turning Big Bang into Big Bounce: I. Classical Dynamics
Piotr Dzierzak, Przemyslaw Malkiewicz, Wlodzimierz Piechocki
The big bounce (BB) transition within a flat Friedmann-Robertson-Walker model is analyzed in the setting of loop geometry underlying the loop cosmology. We solve the constraint of…
