Vertex Operators for AdS3 Background With Ramond Ramond Flux

In order to study vertex operators for the Type IIB superstring on AdS space, we derive supersymmetric constraint equations for the vertex operators in AdS3xS3 backgrounds with Ramond-Ramond flux, using Berkovits-Vafa-Witten variables. These constraints are solved to compute the vertex operators and show that they satisfy the linearized D=6, N=(2,0) equations of motion for a supergravity and tensor multiplet expanded around the AdS3xS3 spacetime.
