摘要
设C和D为余代数,M为C-D-双余模.该文给出了正规三角矩阵余代数T=(CM0D)上余导子的具体结构,并建立T的余导子与C、D和M上相关概念的具体关系.
Let C and D be coalgebras,and M a C-D-bicomodule.In this paper,the specific form of coderivations of the formal triangular matrix coalgebra T=(CM0D) is provided and the relationship between the coderivations of T and those of C,D and M in detail is established.
