The LQC evolution operator of FRW universe with positive cosmological constant
Wojciech Kaminski, Tomasz Pawlowski
The self-adjointness of an evolution operator corresponding to the model of flat FRW universe with massless scalar field and cosmological constant quantized in the framework…

Quantum constraints, Dirac observables and evolution: group averaging versus Schroedinger picture in LQC
Wojciech Kaminski, Jerzy Lewandowski, Tomasz Pawlowski
A general quantum constraint of the form (realized in particular in Loop Quantum Cosmology models) is studied. Group Averaging is applied…

Quantum field theory on a cosmological, quantum space-time
Abhay Ashtekar, Wojciech Kaminski, Jerzy Lewandowski
In loop quantum cosmology, Friedmann-LeMaitre-Robertson-Walker (FLRW) space-times arise as well-defined approximations to specific \emph{quantum} geometries. We initiate the develo…
