Classical stability of stringy wormholes in flat and AdS spaces
arXiv:hep-th/0301191
Abstract
We study small fluctuations of the stringy wormhole solutions of graviton-dilaton-axion system in arbitrary dimensions. We show under O()-symmetric harmonic perturbation that the Euclidean wormhole solutions are unstable in flat space irrespective of dimensions and in anti de Sitter space of .
