Lie 2-代数研究综述

A review of Lie 2-algebras

Honglei Lang, Zhangju Liu

摘要:

首先给出了李$2$ -代数的两个等价定义,李代数的范畴化和$2$ -项$L_\infty$ -代数.然后分别从李群胚上的$2$ -格流形、Courant代数胚、同伦Poisson流形和仿射多向量场出发,给出了四类不同的李$2$ -代数.此外,我们回顾了李$2$ -代数的上同调理论,并分析了它的低次情形。讨论了严格李$2$ -代数到严格李$2$ -群的积分问题。

英文摘要:

We first recall two equivalent definitions of Lie $2$-algebras, categorification of Lie algebras and $2$-term $L_\infty$-algebras. Then we present four different kinds of Lie $2$-algebras from $2$-plectic manifolds, Courant algebroids, homotopy Poisson manifolds and affine multivector fields on a Lie groupoid respectively. Moreover, we recall the cohomology theory of Lie $2$-algebras and analyze its lower degree cases. The integration of strict Lie $2$-algebras to strict Lie $2$-groups is also discussed.
