Surface defects from fractional branes. Part II
Abstract A generic half-BPS surface defect of N $$ \mathcal{N} $$ = 4 supersymmetric U(N ) Yang- Mills theory is described by a partition of N = n 1 + . . . + n M and a set of 4M continuous parameters. We show that such a defect can be realized by n I stacks of fractional D3-branes in Type II B stri...
