Covariant path integrals and black holes
F. Vendrell, M. E. Ortiz
The thermal nature of the propagator in a collapsed black-hole spacetime is shown to follow from the non-trivial topology of the configuration space in tortoise coordinates by usin…

Some exact results on the CGHS black-hole radiation
F. Vendrell
Theorems on the emission of massless scalar particles by the CGHS black hole are presented. The convergence of the mean number of particles created spontaneously in an arbitrary st…

A black hole in two-dimensional space-time
F. Vendrell
An imploding shell of radiation is shown to create a 2-D black hole within the framework of the ``R=T'' theory. The radius of the horizon is given by 1/(2M), where M is the mass of…
