On solvable models of type-IIB superstring in NS-NS and R-R plane wave backgrounds

We consider type-IIB string in the two plane-wave backgrounds which may be interpreted as special limits of the AdS3 × S3 supported by the NS-NS or R-R 3-form backgrounds. The NS-NS plane-wave string model is equivalent to a direct generalization of the Nappi-Witten model, with its spectrum being si...
