摘要
Let （C, C） be a braided monoidal category. The relationship between the braided Lie algebra and the left Jacobi braided Lie algebra in the category （C, C） is investigated. First, a braided C2-commutative algebra in the category （C, C） is defined and three equations on the braiding in the category （C, C） are proved. Secondly, it is verified that （A, [, ] ） is a left （strict） Jacobi braided Lie algebra if and only if （A, [, ] ） is a braided Lie algebra, where A is an associative algebra in the category （C, C）. Finally, as an application, the structures of braided Lie algebras are given in the category of Yetter-Drinfel＇d modules and the category of Hopf bimodules.
设(C,C)为辫子张量范畴,研究辫子张量范畴中辫子李代数和左Jacobi辫子李代数之间的关系.首先,引入了一个新的定义即辫子张量范畴中的辫子平方交换的代数并得到3个关于辫子的等式.其次,证明了对于辫子张量范畴中的结合代数A,(A,[,])是辫子李代数当且仅当(A,[,])是左Jacobi辫子李代数.最后,作为上述结果的应用,给出了Yetter-Drinfel'd模范畴和Hopf双模范畴中辫子李代数的具体结构.
