经典群幂零轨道模空间的箭图理论

Quiver Theories for Moduli Spaces of Classical Group Nilpotent Orbits

Amihay Hanany, Rudolph Kalveks

摘要:

我们从经典群幂零轨道的模空间的角度出发,用希尔伯特级数和生成函数来描述它们。我们回顾了已建立的Higgs和Coulomb分支理论对A系列幂零轨道的构造。我们提出了系统的建设BCD系列幂零轨道上的希格斯分支的规范分区定义的Higgs理论,本文收集早期的工作到一个系统的框架,填补空白,并提供了一个完整的治疗。我们发现新的库仑分支建设上述最小幂零轨道,包括一些扭曲的仿射Dynkin图的基础上。我们还讨论了这些希格斯和库仑分支建设之间的3D镜像对称性方面,并探讨对偶和其他关系,如HyperKahler concentrations,颤抖之间。本文分析了秩为4的所有经典群幂零模空间,给出了它们的未加细Hilbert级数和分解为不可约表示和/或Hall Littlewood多项式的特征标的最高权生成函数.

英文摘要:

We approach the topic of Classical group nilpotent orbits from the perspective of their moduli spaces, described in terms of Hilbert series and generating functions. We review the established Higgs and Coulomb branch quiver theory constructions for A series nilpotent orbits. We present systematic constructions for BCD series nilpotent orbits on the Higgs branches of quiver theories defined by canonical partitions; this paper collects earlier work into a systematic framework, filling in gaps and providing a complete treatment. We find new Coulomb branch constructions for above minimal nilpotent orbits, including some based upon twisted affine Dynkin diagrams. We also discuss aspects of 3d mirror symmetry between these Higgs and Coulomb branch constructions and explore dualities and other relationships, such as HyperKahler quotients, between quivers. We analyse all Classical group nilpotent orbit moduli spaces up to rank 4 by giving their unrefined Hilbert series and the Highest Weight Generating functions for their decompositions into characters of irreducible representations and/or Hall Littlewood polynomials.
