Black holes and covariance in effective quantum gravity: A solution without Cauchy horizons
Cong Zhang, Jerzy Lewandowski, Yongge Ma +1
The issue of general covariance in effective quantum gravity models within the Hamiltonian framework is addressed. The previously proposed equations for the covariance condition in…
Black Holes and Covariance in Effective Quantum Gravity
Cong Zhang, Jerzy Lewandowski, Yongge Ma +1
The longstanding issue of general covariance in effective models of quantum gravity is addressed, which arises when canonical quantum gravity leads to a semiclassical model describ…
Near Horizon Geometries and Black Hole Holograph
J. Lewandowski, I. Racz, A. Szereszewski
Two quasi local approaches to black holes are combined: Near Horizon Geometries (NHG) and stationary Black Hole Holographs (BHH). Necessary and sufficient conditions on BHH data fo…
Observer's observables. Residual diffeomorphisms
Paweł Duch, Jerzy Lewandowski, Jedrzej Świeżewski
We investigate the fate of diffeomorphisms when the radial gauge is imposed in canonical general relativity. As shown elsewhere, the radial gauge is closely related to the observer…
