The question of whether information is lost in black holes is investigated using Euclidean path integrals. The formation and evaporation of black holes is regarded as a scattering problem with all measurements being made at infinity. This seems to be well formulated only in asymptotically AdS spacetimes. The path integral over metrics with trivial topology is unitary and information preserving. On the other hand, the path integral over metrics with non-trivial topologies leads to correlation… Expand
Quantitative approaches to information recovery from black holes
The evaporation of black holes into apparently thermal radiation poses a serious conundrum for theoretical physics: at face value, it appears that in the presence of a black hole, quantum evolutionExpand
Role of Various Entropies in the Black Hole Information Loss Problem
In a recent paper Hawking has argued that there is no information loss in black holes in asymptotically AdS spacetimes. We remind that there are several types of information (entropy) in statisticalExpand
Information recovery from black holes
We argue that if black hole entropy arises from a finite number of underlying quantum states, then any particular such state can be identified from infinity. The finite density of states implies aExpand
Remarks on the black hole information problem
String theory provides numerous examples of duality between gravitational theories and unitary gauge theories. To resolve the black hole information paradox in this setting, it is necessary to betterExpand
INFORMATION RECOVERY FROM BLACK HOLES
We argue that if black hole entropy arises from a finite number of underlying quantum states, then any particular such state can be identified from infinity. The finite density of states implies aExpand
About the Black Hole Information Paradox: A Review of S. W. Hawking, Information Loss in Black Holes, hep-th/0507171
The information paradox of black holes was raised in 1975 by S. W. Hawking. His argument was based on the fact that particle emission from a black hole, so called the Hawking radiation, cannot conveyExpand
Information Loss and Tunneling Radiation of the Non-Stationary Dilaton-Maxwell Black Hole
Taking the self-gravitational interaction and unfixed background space–time into account, we discuss the tunneling radiation of the Dilaton–Maxwell black hole by the Hamilton–Jacobi method. TheExpand
The Black hole information paradox
After a brief reminscence about work with K. Sato 25 years ago on the monopole problem and inflation, a discussion is given of the black hole information paradox. It is argued that, quite generally,Expand
Black holes: Black holes, entropy, and information
Black holes are a continuing source of mystery. Although their classical properties have been understood since the 1970's, their quantum properties raise some of the deepest questions in theoreticalExpand
Entropy Conservation of Linear Dilaton Black Holes in Quantum Corrected Hawking Radiation
It has been shown recently that information is lost in the Hawking radiation of the linear dilaton black holes in various theories when applying the tunneling formalism of Parikh and Wilczek withoutExpand
