Abstract

We present a supersymmetric and -symmetric D-string action on in supercoset construction. As in the previous work of the super D-string action in the flat background, the super D-string action on can be transformed to a form of the IIB Green-Schwarz superstring action with the covariant tension on through a duality transformation. In order to understand a part of the duality transformation as SO(2) rotation of N=2 spinor coordinates, it seems to be necessary to fix the -symmetry in a gauge condition which simplifies the classical action. This is the article showing for the first time that there exists S-duality in type IIB superstring theory in a curved background whose validity has been conjectured in the past but not shown so far in an explicit way.
