S-Duality and Exact Type IIB Superstring Backgrounds

Abstract

A geometrical approach in the non-symmetric connection framework is employed to examine the issue of higher order ${\alpha }^{\prime }$ corrections to D=10 type IIB superstring backgrounds with a covariantly constant null Killing isometry and non-zero Ramond-Ramond field content. These describe generalized supersymmetric string waves and were obtained recently by us through the S-duality transformation of purely NS-NS plane wave backgrounds. We find that the backgrounds are exact subject to the existence of certain field redefinitions and provided certain restrictive conditions are satisfied.
