摘要: 基于复数域上三维李双代数的结构分类, 利用李双代数Atiyah class为零的充要条件, 计算所有复数域上三维李双代数的Atiyah class.

关键词: 李双代数, Atiyah class, 李代数上同调

Abstract: Based on the structure classification of three dimensional Lie bialgebras over C, we calculated the Atiyah classes of all three dimensional Lie bialgebras over C by using a sufficient and necessary condition for the Atiyah class of a Lie bialgebra to be zero.

Key words:  , Lie bialgebra, Atiyah class, Lie algebra cohomology
