稳定映射、Q算子与范畴 O

Stable maps, Q-operators and category O

David Hernandez

AI总结:

本文受 Maulik-Okounkov 稳定映射启发,在量子仿射代数范畴 O 中构造可逆且谱参数有理依赖的代数稳定映射,并由此得到新 R 矩阵、预基本表示的交换性及范畴化 QQ* 系统。

摘要:

受与箭图簇相关的 Maulik-Okounkov 稳定映射启发,我们在任意无扭量子仿射代数的 Borel 子代数的范畴 O 中,在表示的张量积上定义并构造了代数稳定映射。我们的表示论构造基于对 Cartan-Drinfeld 子代数作用的研究。我们证明了代数稳定映射是可逆的,并且有理地依赖于谱参数。作为应用,我们在范畴 O 中获得了新的 R 矩阵,并确立了一大族单模(包括与 Q 算子相关的预基本表示)作为 Cartan-Drinfeld 子代数的表示一般地交换。我们还依据所构造的 R 矩阵建立了范畴化的 QQ* 系统。

英文摘要:

Motivated by Maulik-Okounkov stable maps associated to quiver varieties, we define and construct algebraic stable maps on tensor products of representations in the category O of the Borel subalgebra of an arbitrary untwisted quantum affine algebra. Our representation-theoretical construction is based on the study of the action of Cartan-Drinfeld subalgebras. We prove the algebraic stable maps are invertible and depend rationally on the spectral parameter. As an application, we obtain new R-matrices in the category O and we establish that a large family of simple modules, including the prefundamental representations associated to Q-operators, generically commute as representations of the Cartan-Drinfeld subalgebra. We also establish categorified QQ*-systems in terms of the R-matrices we construct.
