Dressed metric predictions revisited
Wojciech Kamiński, Maciej Kolanowski, Jerzy Lewandowski
It was recently shown that the volume operator of loop quantum cosmology (LQC) and all its positive powers are ill-defined on physical states. In this paper, we investigate how it…
Elementary proof of symmetry of the off-diagonal Seeley-DeWitt (and related Hadamard) coefficients
Wojciech Kamiński
We will prove in an elementary way that off-diagonal Seeley-DeWitt and Hadamard coefficients are (sesqui-)symmetric for smooth manifolds of arbitrary signature.
Operator Spin Foam Models
Benjamin Bahr, Frank Hellmann, Wojciech Kamiński +2
The goal of this paper is to introduce a systematic approach to spin foams. We define operator spin foams, that is foams labelled by group representations and operators, as the mai…
The flat FRW model in LQC: the self-adjointness
Wojciech Kamiński, Jerzy Lewandowski
The flat FRW model coupled to the massless scalar field according to the improved, background scale independent version of Ashtekar, Pawlowski and Singh is considered. The core of…
