我们将一个一元范畴H λ与sl * p或sl∞的每一个优势积分权λ联系起来。这些范畴,用平面图定义,自然作用于与λ相关的简并切环Hecke代数的模的范畴。我们证明了在sl∞情况下,d阶Heisenberg代数嵌入到H λ的Grothendieck环中,其中d是λ的阶。范畴H λ可以看作是描述退化环切Hecke代数模范畴之间的归纳和限制函子及其自然变换的图形演算。作为这一工具的应用,我们证明了一个关于简并切环Hecke代数中心化器的新结果。
We associate a monoidal category H λ to each dominant integral weight λ of sl ˆ p or sl∞. These categories, defined in terms of planar diagrams, act naturally on categories of modules for the degenerate cyclotomic Hecke algebras associated to λ. We show that, in the sl∞ case, the level d Heisenberg algebra embeds into the Grothendieck ring of H λ, where d is the level of λ. The categories H λ can be viewed as a graphical calculus describing induction and restriction functors between categories of modules for degenerate cyclotomic Hecke algebras, together with their natural transformations. As an application of this tool, we prove a new result concerning centralizers for degenerate cyclotomic Hecke algebras.
