Maruyoshi-Song flows and defect groups of $$ {\mathrm{D}}_{\mathrm{p}}^{\mathrm{b}} $$(G) theories

A bstract We study the defect groups of $$ {D}_p^b D p b ( G ) theories using geometric engineering and BPS quivers. In simple case when b = h ∨ ), we use quivers theory to see that group is compatible with a known Maruyoshi-Song flow. To extend where ≠ similar flow conjecture are given by those [ k ] theories. cases n , E 6 8 cross check our result calculating looking at cokernel their intersection matrix.
