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…

Generalized 2d-dilaton models, the true black hole and quantum integrability
M. O. Katanaev, W. Kummer, H. Liebl +1
All 1+1 dimensional dipheomorphism-invariant models can be viewed in a unified manner. This includes also general dilaton theories and especially spherically symmetric gravity (SSG…
