| Popis: | Codimension two defects of the $(0,2)$ six dimensional theory $\mathscr{X}[\mathfrak{j}]$ have played an important role in the understanding of 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 $\mathscr{X}[\mathfrak{j}], \mathfrak{j} \in A,D,E$. Comment: 74pp, lots of tables detailing order reversing duality; (v2) Acknowledgement added. Notation simplified, refs added, minor fixes ; (v3) Minor changes, version accepted in JHEP. I thank the referee for helpful comments towards improving presentation |
