Notes on Dilaton Quantum Cosmology
Gabriel Catren, Claudio Simeone
In these notes we address the canonical quantization of the cosmological models which appear as solutions of the low energy effective action of closed bosonic string theory (dilato…
Thin-shell wormholes in dilaton gravity
Ernesto F. Eiroa, Claudio Simeone
In this work we construct charged thin-shell Lorentzian wormholes in dilaton gravity. The exotic matter required for the construction is localized in the shell and the energy condi…
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…
