标题： Folding Orthosymplectic Quivers

摘要： 将一个单连通箭图的相同腿折叠起来会产生一个具有非单连通边的箭图。到目前为止，这种研究主要集中在包含幺正规范群的箭图上。本文研究了正交辛箭图的折叠，从而产生了一类新的箭图。这是通过在弦系统中相交镜像流形实现的。文中介绍了这些非单连通正交辛箭图的单极公式。一些折叠后的箭图的考夫曼分支是例外代数的最小幂零轨道闭包，从而为这些基本模空间提供了新的构造方法。此外，一类广义折叠正交辛箭图被证明是4维$\mathcal{N}=2$理论的Higgs分支的一种新的磁箭图实现。某些族的Hasse（相位）图通过箭图减法以及弦系统的Kraft-Procesi过渡得出。 显示英文摘要

摘要： 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 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 new magnetic quiver realisation of Higgs branches of 4d $\mathcal{N}=2$ theories. The Hasse (phase) diagrams of certain families are derived via quiver subtraction as well as Kraft-Procesi transitions in the brane system.
