- Title
Quantization of open strings in time-dependent black holes.

- Abstract
In this paper, the open string is quantized in a time-dependent black hole background. By time-dependent black hole, one means a Vaydia geometry in the adiabatic approximation, which in 2 + 1 dimensions is a BTZ black hole with a time-dependent mass. The worldsheet two-point function is derived and it is shown to have the same type of singularity as the flat space one. However, the equal times two-point function depends on the particular Cauchy surface where the worldsheet fields are defined. Finite temperature effects are incorporated through the Liouville–von Neumann approach to nonequilibrium thermodynamics.
