Progress and problems in quantum gravity
Wolfgang Kummer
From the point of view of an uncompromising field theorist quantum gravity is beset with serious technical and, above all, conceptual problems with regard especially to the meaning…
How to approach Quantum Gravity - Background independence in 1+1 dimensions
D. Grumiller, W. Kummer
The application of quantum theory to gravity is beset with many technical and conceptual problems. After a short tour d'horizon of recent attempts to master those problems by the i…
Supersymmetric black holes in 2D dilaton supergravity: baldness and extremality
L. Bergamin, D. Grumiller, W. Kummer
We present a systematic discussion of supersymmetric solutions of 2D dilaton supergravity. In particular those solutions which retain at least half of the supersymmetries are groun…
The Classical Solutions of the Dimensionally Reduced Gravitational Chern-Simons Theory
D. Grumiller, W. Kummer
The Kaluza-Klein reduction of the 3d gravitational Chern-Simons term to a 2d theory is equivalent to a Poisson-sigma model with fourdimensional target space and degenerate Poisson…
Graded Poisson-Sigma Models and Dilaton-Deformed 2D Supergravity Algebra
L. Bergamin, W. Kummer
Fermionic extensions of generic 2d gravity theories obtained from the graded Poisson-Sigma model (gPSM) approach show a large degree of ambiguity. In addition, obstructions may red…
Dilaton Gravity in Two Dimensions
D. Grumiller, W. Kummer, D. V. Vassilevich
The study of general two dimensional models of gravity allows to tackle basic questions of quantum gravity, bypassing important technical complications which make the treatment in…
