摘要：
Exact solutions of the string equations of motion in a specific Lorentzian wormhole background are obtained. These include both closed and open string configurations. Perturbations about some of these configurations are investigated using a recently developed manifestly covariant formalism. Finally, the generalized Raychaudhuri equations for the corresponding string world sheet deformations are written down and analyzed briefly.
