Perturbation of pulsating strings

Abstract We discuss semiclassical quantization of circular pulsating strings in $$ \text {AdS}_3 \times \text {S}^3 $$ AdS3×S3 background with and without the Neveu-Schwarz–Neveu-Schwarz (NS–NS) flux. We find the equations of motion corresponding to the quadratic action in bosonic sector in terms of...
