Four-Dimensional Dilatonic Black Holes in Gauss-Bonnet Extended String Gravity

  • S. O. Alexeyev
  • M. V. Sazhin

Abstract

An internal singularity of a string four-dimensional black hole with second order curvature corrections is investigated. A restriction to a minimal size of a neutral black hole is obtained in the frame of the model considered. Vacuum polarization of the surrounding space-time caused by this minimal-size black hole is also discussed.
