极Brauer范畴、无穷小辫子与李超代数表示

Polar Brauer categories, infinitesimal braids and Lie superalgebra representations

Gustav Lehrer, Ruibin Zhang

AI总结:

本文通过引入无穷小辫子、优惠券和极点推广Brauer范畴,构造到李(超)代数表示范畴的函子,并统一了不变量理论中的经典图解范畴。

摘要:

我们定义了一类以图为态射的幺半范畴,它们是通过附加无穷小辫子、“优惠券”和极点而对Brauer范畴进行的增强与推广。我们探讨了这些范畴的性质,特别是图解方程。我们从其中某些范畴构造到李代数与李超代数表示范畴的函子。应用包括泛包络超代数中心的图解构造和某些“特征恒等式”,以及对某些张量表示的分析。我们展示了不变量理论中出现的经典图解范畴如何成为我们构造的特例,从而将它们置于一个统一的框架中。

英文摘要:

We define a class of monoidal categories whose morphisms are diagrams, and which are enhancements and generalisations of the Brauer category obtained by adjoining infinitesimal braids, "coupons" and poles. Properties of these categories are explored, particularly diagrammatic equations. We construct functors from certain of them to categories of representations of Lie algebras and superalgebras. Applications include a diagrammatic construction of the centre of the universal enveloping superalgebra and certain "characteristic identities", as well as an analysis of certain tensor representations. We show how classical diagram categories arising in invariant theory are special cases of our constructions, placing them in a single unified framework.
