Information in black hole radiation
Abstract
If black hole formation evaporation can be described by an S matrix, information would be expected to come out in black hole radiation. An estimate shows that it may come out initially so slowly, or else be so spread out, that it would never show up in an analysis perturbative in M_{Planck}/M, or in 1/N for twodimensional dilatonic black holes with a large number N of minimally coupled scalar fields.

Lett. referees' comments, the connection between expansions in inverse mass and in 1/N are spelled out, and a figure is added. An argument against perturbatively predicting even latetime information is also provided, as well as various minor changes.)
