Abstract

We discuss string propagation in the near-horizon geometry generated by Neveu-Schwarz fivebranes, Kaluza-Klein monopoles and fundamental strings. When the fivebranes and KK monopoles are wrapped around a compact four-manifold $\MM$, the geometry is $AdS_3\times S^3/\ZZ_N\times \MM$ and the spacetime dynamics is expected to correspond to a local two dimensional conformal field theory. We determine the moduli space of spacetime CFT's, study the spectrum of the theory and compare the chiral primary operators obtained in string theory to supergravity expectations.
