一般线性李超代数的分次超对偶

Graded super duality for general linear Lie superalgebras

Christopher Leonard

摘要:

本文给出了一般线性李(超)代数的无限秩抛物BGG范畴之间的超对偶等价性的一个新的证明。我们这样做是通过建立一个新的唯一性定理的张量积展开的Brundan,Losev,和韦伯斯特的工作的动机。此外,我们证明了这些BGG范畴具有Koszul分次提升,并且超对偶可以提升到分次等价。

英文摘要:

We provide a new proof of the super duality equivalence between infinite-rank parabolic BGG categories of general linear Lie (super) algebras conjectured by Cheng and Wang and first proved by Cheng and Lam. We do this by establishing a new uniqueness theorem for tensor product categorifications motivated by work of Brundan, Losev, and Webster. Moreover we show that these BGG categories have Koszul graded lifts and super duality can be lifted to a graded equivalence.
