Information loss in black holes due to transition point

Abstract

An interesting theoretical question is the probability of information loss in the black hole due to the transition point. The presented study is an attempt to investigate this subject. When the black hole is exhausted due to Hawking radiation, the entropy carried away by all emissions and string ball is not equal to the entropy in the original black hole. We conclude that the total entropy is not conserved due to the transition point. This means that some information is lost at the corresponding point. Using the Gottesman and Preskill method, the amount of information loss in the black hole at the correspondence point is obtained.
