A Simple Stationary Line Element for the Schwarzschild Geometry, and Some Applications | | Per Kraus

23 Jun 1994 | | Subject: | gr-qc hep-th | | Abstract: | Guided by a Hamiltonian treatment of spherically symmetric geometry, we find a remarkably simple -- stationary, but not static -- form for the line element of Schwarzschild (and Reissner-Nordstrom) geometry. The line element continues smoothly through the horizon; by exploiting this feature we are able to give a very simple and physically transparent derivation of the Hawking radiance. We construct the complete Penrose diagram by enforcing time-reversal symmetry. Finally we outline how an improved treatment of the radiance, including effects of self-gravitation, can be obtained. | | Source: | arXiv, gr-qc/9406042 | | Services: | Forum | Review | PDF | Favorites | |
