Strings on ${\text{AdS}}_3\times {\text{S}}^3\times {\text{S}}^3\times {\text{S}}^1$

Abstract

String theory on ${\mathrm{AdS}}_3\times {\mathrm{S}}^3\times {\mathrm{S}}^3\times {\mathrm{S}}^1$ with pure NS-NS flux and minimal flux through one of the two ${\mathrm{S}}^3$'s is studied from a world-sheet perspective. It is shown that the spacetime spectrum, as well as the algebra of spectrum generating operators, matches precisely that of the symmetric orbifold of ${\mathrm{S}}^3\times {\mathrm{S}}^1$ in the large $N$ limit. This gives strong support for the proposal that these two descriptions are exactly dual to one another.
