1.
Crossed modules and third cohomology of four dimensional Lie algebras
四维李代数的交叉模和三阶上同调群
2.
The paper first gives an equivalent definition of crossed modules of linear algebras,and then provides a general way of calculation for any crossed modules of linear algebras,and finally the paper proves that the equivalent set of crossed modules of general linear algebra is trivial and gets the third cohomology.
给出交叉模的一个等价定义,为具体李代数的交叉模提供一种一般性的计算方法,并用这种方法证明了一般线性代数的交叉模的等价类集合是平凡的,同时利用三阶上同调群与交叉模等价类集的一一对应关系,得到了一般线性代数的三阶上同调群。
3.
According to the definition of crossed modules of Lie algebras,it is proved that there is only one equivalent class of crossed modules of triangular Lie algebras,and that its third cohomology is trivial.
根据李代数的交叉模的定义,计算出上三角矩阵代数的交叉模等价类只有一个,相应的三阶上同调群平凡。
