摘要: 先给出3-李2-代数表示的定义, 再利用表示给出3-李2-代数2-阶闭链的定义, 最后给出3-李2-代数1-参数无穷小形变的充分必要条件.

关键词: 3-李2-代数, 表示, 2-阶闭链, 形变

Abstract: Firstly, the definition of the representation of 3-Lie 2-algebras was given. Secondly, the definition of 2-cocycle of 3-Lie 2-algebras was given by using the representation. Finally, the necessary and sufficient conditions of 1-parameter infinitesimal deformations of 3-Lie 2-algebras were given.

Key words: 3-Lie 2-algebras, representation, 2-cocycle, deformation
