The problem of time and gauge invariance in the quantization of cosmological models. II. Recent developments in the path integral approach
T. P. Shestakova, C. Simeone
The paper is the second part of the work devoted to the problem of time in quantum cosmology. Here we consider in detail two approaches within the scope of Feynman path integration…
The problem of time and gauge invariance in the quantization of cosmological models. I. Canonical quantization methods
T. P. Shestakova, C. Simeone
The paper is the first of two parts of a work reviewing some approaches to the problem of time in quantum cosmology, which were put forward last decade, and which demonstrated thei…
Cylindrical thin-shell wormholes
Ernesto F. Eiroa, Claudio Simeone
A general formalism for the dynamics of non rotating cylindrical thin-shell wormholes is developed. The time evolution of the throat is explicitly obtained for thin-shell wormholes…
Liouville theory and logarithmic solutions to Knizhnik-Zamolodchikov equation
Gaston Giribet, Claudio Simeone
We study a class of solutions to the SL(2,R)_k Knizhnik-Zamolodchikov equation. First, logarithmic solutions which represent four-point correlation functions describing string scat…
