Stability analysis of a stringy black hole

  title={Stability analysis of a stringy black hole},
  author={Rue‐Ron Hsu and Green Huang and Wei Fu Lin and Chin-Rong Lee},
  journal={Classical and Quantum Gravity},
The authors investigate the stability of charged black holes in two-dimensional heterotic string theories that were recently discussed by McGuidan et al. (1992). In the framework of small time-dependent perturbation, they find that these black holes are linearly stable.

Instability of two-dimensional heterotic stringy black holes
We solve the eigenvalue problem of general relativity for the case of charged black holes in two-dimensional heterotic string theory, derived by McGuigan et al. For the case of , we find a physically
Quasinormal frequencies of asymptotically flat two-dimensional black holes
We discuss whether the minimally coupled massless Klein-Gordon and Dirac fields have well defined quasinormal modes in single horizon, asymptotically flat two-dimensional black holes. To get the
Linear stability of Mandal–Sengupta–Wadia black holes
In this paper, the linear stability of static Mandal–Sengupta–Wadia (MSW) black holes in (2 + 1)-dimensional gravity against circularly symmetric perturbations is studied. Our analysis only applies


Two-dimensional charged black holes in string theory.
Exact string solutions corresponding to two-dimensional electrically charged black holes are constructed at √s =1, √2, and √3 using the Higgs boson standard.
Classical solutions of 2-dimensional string theory
We present an exact one-parameter family of solutions to the classical graviton-dilaton system in two dimensions. The solution can be identified as a black hole. We present the solution both in a

An exact conformal field theory describing a black hole in two-dimensional space-time is found as an SL(2,{ital openR})/U(1) gauged Wess-Zumino-Witten model, which should be regarded as an analog of the extreme Reissner-Nordstroem black hole of four-dimensional general relativity.
The Mathematical Theory of Black Holes
In a course of lectures on the ‘underlying mathematical structures of classical gravitation theory’ given in 1978, Brandon Carter began with the statement ‘If I had been asked five years ago to
