Multi-exponential models of (1+1)-dimensional dilaton gravity and Toda-Liouville integrable models
V. de Alfaro, A. T. Filippov
The general properties of a class of two-dimensional dilaton gravity (DG) theories with multi-exponential potentials are studied and a subclass of these theories, in which the equa…
Quantization of the String Inspired Dilaton Gravity and the Birkhoff Theorem
Marco Cavaglia, Vittorio de Alfaro, Alexandre T. Filippov
We develop a simple scheme of quantization for the dilaton CGHS model without scalar fields, that uses the Gupta-Bleuler approach for the string fields. This is possible because th…
The Birkhoff Theorem in the Quantum Theory of Two-Dimensional Dilaton Gravity
Marco Cavaglia, Vittorio de Alfaro, Alexandre T. Filippov
In classical two-dimensional pure dilaton gravity, and in particular in spherically symmetric pure gravity in d dimensions, the generalized Birkhoff theorem states that, for a suit…
Time Gauge Fixing and Hilbert Space in Quantum String Cosmology
Marco Cavaglia`, Vittorio de Alfaro
Recently the low-energy effective string theory has been used by Gasperini and Veneziano to elaborate a very interesting scenario for the early history of the universe (``birth of…
Quantization of a 2D Minisuperspace Model in Dilaton-Einstein Gravity
Marco Cavaglia`, Vittorio de Alfaro
We investigate a minisuperspace model of Einstein gravity plus dilaton that describes a static spherically symmetric configuration or a Kantowski - Sachs like universe. We develop…
Quantization of the Schwarzschild Black Hole
Marco Cavaglia`, Vittorio de Alfaro, Alexandre T. Filippov
We quantize by the Dirac - Wheeler-DeWitt method the canonical formulation of the Schwarzschild black hole developed in a previous paper. We investigate the properties of the opera…
