Description

This meeting which is ICTS-IISc joint program will discuss recent progress on the black-hole information paradox, and the question of whether AdS/CFT can provide a useful description of the interior of black holes.Long ago, Hawking found that the thermal radiation from black-holes appeared to be in conflict with the unitarity of quantum mechanics. It was believed, especially after the advent of the AdS/CFT correspondence, that Hawking's calculation was not precise enough to provide a paradox, and that small effects in the CFT would reconcile Hawking radiation with unitarity.Recently, there have been several claims, starting with the work of Mathur, and followed by the work of Marolf, Polchinski and others that this is impossible; rather unitarity implies that quantum effects modify the structure of the horizon of the black-hole.This meeting will take stock of the claims and counter-claims in the literature. Broadly speaking, the following positions have been articulated:1) quantum effe...
