量子sl(2)的一个奇分类

An odd categorification of quantum sl(2)

Alexander P. Ellis, Aaron D. Lauda

摘要:

本文定义了一个2-范畴,它将Clark和Wang引入的sl(2)的覆盖Kac-Moody代数进行范畴化。这种范畴化形成了Kang、Kashiwara和Oh所表述的超2范畴的结构。超2-范畴结构引入了一个(Z x Z_2)-分次,使它的Grothendieck群具有Z x Z_2的群代数上的自由模的结构.通过将Z_2-作用特化成+1或-1,构造特化成sl(2)的“奇”范畴和osp(1)的超范畴|(2)分别。

英文摘要:

We define a 2-category that categorifies the covering Kac-Moody algebra for sl(2) introduced by Clark and Wang. This categorification forms the structure of a super-2-category as formulated by Kang, Kashiwara, and Oh. The super-2-category structure introduces a (Z x Z_2)-grading giving its Grothendieck group the structure of a free module over the group algebra of Z x Z_2. By specializing the Z_2-action to +1 or to -1, the construction specializes to an "odd" categorification of sl(2) and to a supercategorification of osp(1|2), respectively.
