Abstract
Codimension two defects of the (0, 2) six dimensional theory X[j] have played an important role in understanding dualities for certain \( \mathcal{N} \) = 2 SCFTs in four dimensions. These defects are typically understood by their behaviour under various dimensional reduction schemes. In their various guises, the defects admit partial descriptions in terms of singularities of Hitchin systems, Nahm boundary conditions or Toda operators. Here, a uniform dictionary between these descriptions is given for a large class of such defects in X[j], j ∈ A, D, E.
