摘要

String theory on AdS3 × S3 × S3 × S1 with two units of NS flux through each of the two 3-spheres (and one unit of NS flux supporting the AdS3 factor) was recently argued to be exactly dual to the symmetric orbifold of eight free fermions and two bosons. This setup is interesting since it allows for a simple NS-R description. In this paper we study the spherical D-branes of this theory, and identify them with branes in the dual symmetric orbifold theory. We also comment briefly on the AdS2 branes.
