Abstract

We summarize some (mostly geometric) facts underlying the relation between \(2\)D integrable sigma models and generalized Gross–Neveu models, emphasizing connections to the theory of nilpotent orbits, Springer resolutions, and quiver varieties. This is meant to shed light on the general setup when this correspondence holds.

Sigma 模型为 Gross-Neveu 模型。二

摘要

我们总结了\(2\) D 可积 sigma 模型和广义 Gross-Neveu 模型之间关系的一些（主要是几何）事实，强调与幂零轨道、施普林格分辨率和箭袋簇理论的联系。这是为了在该对应关系成立时阐明一般设置。
