Hawking radiation and Hawking flux from spherical reduction
W. Kummer, D. V. Vassilevich
Using heat kernel techniques we show that the relation between Hawking temperature and radiation flux known from Einstein gravity in D dimensions can be reproduced from the spheric…

Exact Path Integral Quantization of 2-D Dilaton Gravity
W. Kummer, H. Liebl, D. V. Vassilevich
We demonstrate that in the absence of `matter' fields to all orders of perturbation theory and for all 2D dilaton theories the quantum effective action coincides with the classical…
