Liouville black holes

“…One can include quantum gravitational effects by considering a functional integral over the field configurations of the metric, ψ, and φ fields [24]. The path integral is…”

2d Quantum Gravity Coupled to Renormalizable Matter Fields

“…only through their central charge c = N and we have only included them in order to be able to vary the total central charge of the matter sector. The model (33) has been considered in various contexts [14,15]. Let us here review the part we need for the target space formulation.…”

Lower dimensional black holes

“…In each approach the Ricci scalar becomes a non-vanishing function of the co-ordinates over some region of spacetime, permitting the spacetime to develop interesting features such as black-hole horizons and singularities. Considerable progress can be made in the quantization of such theories coupled to matter [20,21,22,23], providing an attractive arena for testing ideas about quantum gravity [24].…”
