Query: Defects in Chern-Simons theory, gauged WZW models on the brane, and
  level-rank duality   We consider Hanany-Witten setups of 3- and 5-branes in type IIB string theory
that realize N=(1,0),(2,0) and (1,1) gauged WZW models in 1+1 dimensions. The
gauged WZW models arise as theories residing on the boundary of D3 branes
ending on D5 branes. From the point of view of low energy dynamics the D5
branes play the role of half-BPS co-dimension-1 defects (domain walls) in 3d
N=1 or N=2 Chern-Simons theories. Extending the analysis of previous works on
the subject of boundary conditions in (supersymmetric) Chern-Simons theory, we
discuss in detail the field theory construction of a large class of
Chern-Simons domain wall theories and its embedding in open string dynamics.
Finally, we exhibit how standard brane moves that result to 3d Seiberg duality,
translate in our setup to a generalized level-rank duality in gauged-WZW
models.
