چکیده

We derive the world-volume theory, the (non)-extremal entropy and background geometry of black holes and black strings constructed out of the NS IIA fivebrane within the framework of matrix theory. The CFT description of strings propagating in the black hole geometry arises as an effective field theory.

5D Black Holes and Strings with Higher Derivatives

We find asymptotically flat black hole and string solutions to 5D supergravity in the presence of higher derivative terms. In some cases, including the fundamental heterotic string solution, the higher derivative terms smooth out naked singularities into regular geometries carrying zero entropy. We also compute corrections to the entropy of 5D CalabiYau black holes, and discuss the relation to ...

Stringy Corrections to Kaluza-Klein Black Holes

We consider string theory corrections to 4D black holes which are solutions of the 5D vacuum Einstein equations. We find that the corrections vanish only for the extremal electric solution. We also show that for the non-extremal electric black hole the mass corrections are related to the charge corrections. The implications to string states counting and the correspondence principle for black ho...

Comments on Black Holes in Matrix Theory

The recent suggestion that the entropy of Schwarzschild black holes can be computed in matrix theory using near-extremal D-brane thermodynamics is examined. It is found that the regime in which this approach is valid actually describes black strings stretched across the longitudinal direction, near the transition where black strings become unstable to the formation of black holes. It is argued ...

Dilatonic Black Holes , Naked Singularities and Strings

We extend a previous calculation which treated Schwarzschild black hole horizons as quantum mechanical objects to the case of a charged, dilaton black hole. We show that for a unique value of the dilaton parameter a, which is determined by the condition of unitarity of the S matrix, black holes transform at the extremal limit into strings.

Boosts, Schwarzschild Black Holes and Absorption cross-sections in M theory

D dimensional neutral black strings wrapped on a circle are related to (D−1) dimensional charged black holes by boosts. We show that the boost has to be performed in the covering space and the boosted coordinate has to be compactified on a circle with a Lorentz contracted radius. Using this fact we show that the transition between Schwarzschild holes to black p-branes observed recently in M the...
