The GS Type IIB Superstring Action on AdS(3) X S(3) X T(4)
Abstract
We describe the type IIB supergravity background on AdS3 x S3 x T4 using the potentials of AdS3|4 x S3 x T4 and we use the supersolvable algebra associated to AdS3|4 to compute the kappa gauge fixed type IIB string action. From the explicit form of the action we can clearly see how passing from pure NSNS backgrounds to pure RR backgrounds the WZW term disappears.
