【摘要】 研究了李着色代数的交叉模等价类集合中的线性运算.证明了交叉模的等价类集合是一个线性空间,而且它与李着色代数的三阶上同调的零次齐次部分空间同构.作为这个理论的一个应用,刻画了Witt型李着色代数的交叉模,当交换群Γ等于Γ+时,证明了Witt型李着色代数的交叉模等价类只有一个.最后,根据三阶上同调与交叉模之间的同构关系,对Witt型李着色代数的交叉模进行了分类.更多还原

【Abstract】 The linear operations of the equivalent classes of crossed modules of Lie color algebras are studied. The set of the equivalent classes of crossed modules is proved to be a vector space, which is isomorphic with the homogeneous components of degree zero of the third cohomology group of Lie color algebras. As an application of this theory, the crossed modules of Witt type Lie color algebras is described, and the result is proved that there is only one equivalent class of the crossed modules of Witt type Lie color algebras when the abelian group Γ is equal to Γ+. Finally, for a Witt type Lie color algebra, the classification of its crossed modules is obtained by the isomorphism between the third cohomology group and the crossed modules.更多还原
