Phys. Rev. D 55, 6403–6408 (1997)String propagation in an exact four-dimensional black hole backgroundReceived 9 October 1996; published in the issue dated 15 May 1997 We study string propagation in an exact, stringy, four-dimensional dyonic black hole background. The exact solutions in terms of elliptic functions describing string configurations in the J=0 limit are obtained by solving the string equations of motion and constraints. By using the covariant formalism, we also investigate the propagation of physical perturbations along the string in the given curved background. © 1997 The American Physical Society URL:
