Abstract Folding identical legs of a simply-laced quiver creates a quiver with a non-simply laced edge.So far, this has been explored for quivers containing unitary gauge groups.In this paper, orthosymplectic quivers are folded, giving rise to a new family of quivers.
This is realised by intersecting orientifolds in the brane system.The monopole formula for these non-simply laced orthosymplectic quivers is here introduced.Some of the folded quivers have Coulomb branches that are closures of minimal nilpotent orbits of exceptional algebras, thus providing a new construction of these fundamental moduli spaces.
Moreover, a general family of folded orthosymplectic quivers is shown to be a guerlain ideal cologne new magnetic quiver realisation of Higgs branches of 4d N $$ mathcal{N} $$ = 2 theories.The Hasse (phase) diagrams of certain families are derived via quiver subtraction as well as Kraft-Procesi transitions in the brane system.
