Abstract

The puzzles of black-hole evaporation can be studied in the simplified context of 1 + 1 dimensional gravity. The semi-classical equations of Callan et al. provide a consistent description of the evaporation process which we describe in detail. We consider the possibility that black-hole evolution leads to massive stable remnants. We show that such zero-temperature-remnant solutions exist but we also prove that a decaying black hole cannot evolve into one of them. Finally we consider the issue of loss of quantum information behind the global event horizon which develops in these geometries. An analogy with a well-known solvable system shows that there may be less to information than meets the eye.
