Evaporation of a nonsingular Reissner-Nordström black hole and information loss problem

Abstract One of the attractive solutions to information loss problem is that event horizon does not appear in process gravitational collapse and subsequent evaporation once spacetime singularity regularized by some mechanism, as pointed out Hayward Frolov. In this paper, we examine whether Hayward-Frolov scenario holds for a charged black hole. The modeled with Vaidya two kinds regularization central are considered. Analyzing structure evaporating hole, find appropriately Reissner-Nordström “black hole” has no Cauchy horizons, indicating possibility may have sufficient generality solution problem. addition, properties non-singular hole examined detail.
