Inequivalent light-cone gauge-fixings of strings on $Ad{S}_n\times S^n$ backgrounds

Riccardo Borsato, Sibylle Driezen, Ben Hoare +2

Light-cone gauge-fixed sigma-models on $Ad{S}_n\times S^n$ backgrounds play an important role in the integrability formulation of the AdS/CFT correspondence. The string spectrum of t…
