Abstract

String equations for the vertex operators of type IIB on $A d S_{3} \times S^{3}$ background with NS-NS flux are calculated using Berkovits-Vafa-Witten formalism. With suitable field definitions, the linearized field equations for six-dimensional supergravity and a tensor multiplet on $A d S_{3} \times S^{3}$ are recovered from these. We also discuss the massless degrees of freedom that survive the $S^{3}$ Kaluza-Klein compactification and how our vertex operators are related to the vertex operators introduced by Giveon, Kutasov and Seiberg.
