Classical instanton and wormhole solutions of type IIB string theory

摘要

We study the rho=-1 D-brane in type IIB superstring theory. In addition to the RR instanton, we obtain the RR charged wormhole solution in the Einstein frame. This corresponds to the ten-dimensional singular wormhole solution with infinite euclidean action. (C) I997 Elsevier Science B.V.
