Conformal Cyclic Cosmology from Varying Fundamental Constants
Konrad Marosek, Adam Balcerzak
We investigate a bimetric cosmological model in which the gravitational and matter sectors are described by distinct metrics related through a time-dependent function . This…
Fermionic quantum cosmology as a framework for resolving type IV singularities
Paweł Kucharski, Adam Balcerzak
In this paper, we present an innovative approach to resolving type IV singularities in fermionic quantum cosmology. The Eisenhart-Duval lift procedure is employed to construct an e…
Conformal structure of singularities in some varying fundamental constants bimetric cosmologies
Konrad Marosek, Adam Balcerzak
In this paper, we explore the conformal structure of singularities arising from varying fundamental constants using the method of Penrose diagrams. We employ a specific type of bim…
Cosmogenesis as symmetry transformation
Adam Balcerzak, Mateusz Lisaj
We consider the quantized bi-scalar gravity, which may serve as a locally Lorentz invariant cosmological model with varying speed of light and varying gravitational constant. The e…
