Exact Description of Black Holes on Branes II: Comparison with BTZ Black Holes and Black Strings
We extend our recent discussion of four-dimensional black holes bound to a two-brane to include a negative cosmological constant on the brane. We find that for large masses, the solutions are precisely BTZ black holes on the brane, and BTZ ‘black strings’ in the bulk. For smaller masses, there are localized black holes which look like BTZ with corrections that fall off exponentially. We compute...
متن کاملOn black strings & branes in Lovelock gravity
It is well known that black strings and branes may be constructed in pure Einstein gravity simply by adding flat directions to a vacuum black hole solution. A similar construction holds in the presence of a cosmological constant. While these constructions fail in general Lovelock theories, we show that they carry over straightforwardly within a class of Lovelock gravity theories that have (loca...
متن کاملBOUND STATES OF STRINGS AND p-BRANES
The recent discovery of an explicit conformal field theory description of Type II p-branes makes it possible to investigate the existence of bound states of such objects. In particular, it is possible with reasonable precision to verify the prediction that the Type IIB superstring in ten dimensions has a family of soliton and bound state strings permuted by SL(2,Z). The space-time coordinates e...
متن کاملBlack holes in general relativity
What is going on (as of August 2008) at the interface between theoretical general relativity, stringinspired models, and observational astrophysics? Quite a lot. In this mini-survey I will make a personal choice and focus on four specific questions: Do black holes “exist”? (For selected values of the word “exist”.) Is black hole formation and evaporation unitary? Can one mimic a black hole to a...
متن کاملOn the Stability of Black Strings/Branes∗
Some issues on the stability of black string or brane solutions are summarized briefly. The stability of dS/AdS-Schwarzschild black strings has been investigated. Interestingly, the AdS-Schwarzschild black strings turn out to be stable as the horizon size becomes larger than the AdS scale. It is also shown that BTZ black strings in four dimensions are stable regardless of the horizon size. Such...
