Quantum three-dimensional de Sitter space
Maximo Banados, Thorsten Brotz, Miguel Ortiz
We compute the canonical partition function of 2+1 dimensional de Sitter space using the Euclidean Chern-Simons formulation of 3d gravity with a positive cosmol…

Quantization of Black Holes in the Wheeler-DeWitt Approach
Thorsten Brotz
We discuss black hole quantization in the Wheeler-DeWitt approach. Our consideration is based on a detailed investigation of the canonical formulation of gravity with special consi…

Semiclassical Black Hole States and Entropy
T. Brotz, C. Kiefer
We discuss semiclassical states in quantum gravity corresponding to Schwarzschild as well as Reissner Nordström black holes. We show that reduced quantisation of these models is eq…
