@article{Kummer1999HawkingRF, title={Hawking radiation from dilaton gravity in 1 + 1 dimensions: a pedagogical review}, author={Wolfgang Kummer and Dmitri Vassilevich}, journal={Annalen der Physik}, year={1999}, volume={8} }

Hawking radiation in d = 4 is regarded as a well understood quantum theoretical feature of Black Holes or of other geometric backgrounds with an event horizon. On the other hand, the dilaton theory, emerging after spherical reduction, and generalized dilaton theories only during the last years became the subject of numerous studies which unveiled a surprisingly difficult situation. Recently we have found some solution to the problem of Hawking flux in spherically reduced gravity which has the…
