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.

Non-self-adjointness of the Klein-Gordon operator on a globally hyperbolic and geodesically complete manifold. An example
Wojciech Kamiński
We describe a Lorentzian manifold that is globally hyperbolic and geodesically complete, but such that the (minimally coupled) Klein-Gordon operator with the standard domain is not…
